Undetected

Rate this book
When asked what he does for a living, Commander Mark Bishop is deliberately low-key: "I'm in the navy."

But commanding the ballistic missile submarine USS Nevada, keeping its crew trained and focused during 90-day submerged patrols, and being prepared to launch weapons on valid presidential orders, carries a burden of command like few other jobs in the military. Mark Bishop is a man who accepts that responsibility, and carries it well. And at a time when tensions are escalating in the Pacific Rim, the navy is glad to have him.

Mark wants someone to come home to after sea patrols. The woman he has in mind is young, pretty, and very smart. She's a civilian, but she understands life in the navy. And he has a strong sense that life with her would never be boring. But she may be too deep in her work to see the potential in a relationship with him.

Gina Gray would love to be married. She has always envisioned her life that way. But a breakup she didn't see coming has her focusing all her attention on what she does best--ocean science research. She's on the cusp of a breakthrough, and she needs Mark Bishop's perspective and help. Because what she's told the navy she's figured out is only the beginning. If she's right, submarine warfare is about to enter a new and dangerous chapter...

This was actually a lot different than I expected.

Mark Bishop was a very interesting character, as was Gina. They were both so multi-faceted, and I was drawn into their story from page one.

The science and technical part of this was . . . a bit hard to understand at times. But it was still very interesting, and I found myself asking "what if?" several times.

The romance was excellently done. Very low-key and clean, which made me very happy. The love triangle irked me a bit, mostly because I felt terrible for the second guy, lol!

My one critique would be that it was very longgggg, and slightly anticlimactic. I kept expecting something terrible to happen to one of the characters, but . . . it never did. It did definitely climax, but it was a bit lackluster. And the length. At nearly 500 pages, this is a beast. Cutting out a couple of parts would have been helpful in getting the story moving on a little better.

All in all, a very enjoyable read!

Recommended for ages 15+ for romance and comprehension.

CONTENT NOTE: Aside from a few not described kisses, this was completely clean.

If I had to describe this book in one word it would be, "Boring." And that seriously makes me sad. You have no idea how much I wanted to like this book. I kept slogging through hoping it would get better. It never did.

I would say that 90% of the book was about submarines. How they operate, what they do, what life is like in the Navy while on one of them. But you don't discover these facts through the story. They are just laid out like, "Oh, I have all this research that I need to lay out for people". If you like submarines, boy this will be a good book for you. 10 % of this book was the story, and even that was questionable. Gina wants to get married really bad, and she now has two great guys wanting to marry her and she still doesn't get it. She's so smart she almost can't function it seems. Plus, what's with all the security around her? Yes, I understand why they said it was necessary in the book. It was mentioned multiple times, but why? It had no bearing on the book at all. She was never kidnapped, or hurt, or even sought after by people who would harm her. Nothing. Just a lot about how she was at risk and needed security.

Let's look at the great guys for a minute. Now, normally I love when the guys are great in a novel. I'm not one for the rebel type character. But boy, both of these guys were so great they were completely unreal. Neither one would fight for Gina, they were both, "Whoever she picks is going to be lucky, and I'll still be friendly and nice and not hurt at all." It showed a lack of feeling to me, instead of supposedly loving this woman.

Did I mention there is no conflict in this book either? No climax. Nothing happens. She discovers great things, both men and her brother go off to sea, even when a war almost breaks out, it doesn't and nothing happens. In fact, every time the story started to get interesting the author would skip the interesting part and the next thing I knew it was "two weeks later" and the interesting part was over with nothing to show for it.

Content wise it is squeaky squeaky clean. Even the kissing that took place was boring.

Would I buy this? No. Would I recommend this? No.

Beautiful, beautiful book; full of exquisite detail. I will add this disclaimer before going on: this book is not for everyone.

Going on.

I LOVED all of the sonar and submariner life details in this book. I'm utterly in awe of it all, and now, fascinated. I want to know more. Dee Henderson obviously does her research, and does it well. I wouldn't be surprised if, like Gina, she has a book budget, and out of 12 books, finds her information from 1 or 2, but still keeps buying more and more. This is what I think will inevitably turn people off, though. I know of several Dee-readers that won't enjoy this book, because it goes so far into the technical side of Gina's and Mark's lives. That was a huge bonus for me, however, as I enjoy delving into topics such as these.

From the suspense angle, this is not a typical Dee Henderson. It did not have me on the edge of my seat. It was less plot-driven than usual Dee fare, but this book had me completely engrossed. She carefully constructed their world, and I found myself becoming a part of it. The characters pulled the story at an even pace.

I adored Gina and Mark. All of the characters, actually. Mark could be a little pushy at first, but I really enjoyed getting to know his character. Multi-layered person. I would have liked a few more chapters from Gina's perspective, as she was very interesting. I would have liked to learn a little more about her past. I realize though, that Dee often brings her characters around more than once, and there is another Bishop brother, so...

This is the best Henderson book I’ve read in recent years. It still has a few struggles: the beginning is very slow, the male lead’s mature protectiveness of the female gets a wee bit controlling and stifling at times, and the fact that his pet name for her is “precious” had me continually summoning up visions of Gollum...

That said, this is fabulous premise—one of the most unique and realistically compelling I’ve run across in recent years. The book is beautifully structured, and Henderson does an awesome job pacing out both the tense military stuff and the leisurely romance, so that it all fits together perfectly in the end. It’s also, for the most part, a very realistic and thought-provoking look at relationships. Worth the read for anyone who has enjoyed past Henderson books.

1.5 men who needed a bloody turtle slap.

"Gina..." Mark hesitated. "Do you realize you're afraid to get married?" he asked gently. "Daniel would have been a good choice for you. I'm a good choice. When you find there are none of your must-not-haves and all of your must-haves, it's time to say yes. I love you. And I'm confident you'll love me well in return if you let yourself take the step. Say yes and marry me. Your doubts are real, but they won't survive first contact with reality."


- Page 323

"Marry me, Gina. You need me. I want you as my wife. There are worse reasons to get married."
"There are better." She bit her lip. "I don't love you, Mark."
"Yet," he qualified. "You don't love me yet."


- Page 339

Gina, I want to be your husband. And getting married now could be a good buffer for you. You could say 'See my husband about that' when the questions start coming. I can tell the Navy to go through me on any concerns, that I have the authority to speak for you. You'll find life is a lot easier--maybe even happier--if you marry me before this goes any further."
He waited a moment and then smiled. "I'm going to make one last pitch, okay? My best one. Then I'll let this topic drop, I promise." He waited for her to glance up. "I know the package might not be ideal. I'm older, I've been married before. But the 'content', those characteristics you're looking for, are what you want. We share a deep faith in God, a strong work ethic, a sense of ambition, alongside a personal life that is quiet and, for the most part, peaceful. We have a willingness to be open with one each other--a verbal intimacy, if you will--a desire to listen and share what we're thinking and feeling."
....Blah blah you have a pretty smile
"I'm a good risk, Gina. Take a leap and make the decision that your future is with me. Trust me, trust the fact that I love you. I'm not asking you to have everything sorted out and not have any doubts. I don't need that from you. What I need, what I think you need, is a yes."


- Page 346-7


There are just so many problems with this book and, mainly, their relationship. Those quotes above should give a pretty giant indication of exactly what I mean. See, I'm all for the guy realizing that he loves the girl, that she is the one, before the girl comes to the realization that she loves the guy. I like this trope and, actually, it happens all the time. But this was horrible. Mark comes to the realization that he loves Gina months and months before they even start dating. In fact, she's dating someone else and he's all, "Crap. I should have asked her out when I had the chance." All fine and good. He's interested in pursuing a relationship. Lovely. And when exactly did he go from that to, essentially, tricking her into dating him when she's still dating Daniel, begging her not to get engaged till after he got back off-duty, and proposing marriage as more a best-case scenario "This would be useful" kind of deal?? He could see that his talk of marriage, and actually dating, was worrying her; upsetting her, and yet he wouldn't give it a rest until far far after he should have. If he actually loved her, he would shut up, back off, and let her come to her own decision, without his nagging and begging. Instead, it feels like he talks about him loving her and how great their life would be together that she just, all too conveniently, starts to believe it too? I don't even know. It was weird.
And, weirdly, besides the fact that Mark was waaay too insistent, he was "perfect". Like, no flaws. Gina didn't have any either. Neither did Daniel, for that matter. Him and Mark were totally chill about moving in on the others' girl, so long as they did it slow like. They had "man-code" or some shite, so may the best man win, we'll still be friends no matter who she picks, etc abounded. Except I have a brother and I know that's not really how it works. Maybe, MAYBE, one guy would feel like that, but definitely not both of them.
Thankfully, the Christian element was not heavy-handed. A few prayers here and there, but none of the preachy stuff.
As far as plot went, it was so boring, I could have probably watched "Arrow" on pause and been more interested. It started off pretty good and some of the submarine elements, Gina's work, and solar flares(STAAAAARGATE) were interesting, but it went NO WHERE. This was a nearly 500 page book with almost nothing happening. Even when I thought something exciting or dangerous might happen in the last 100 pages, there was still nothing. Bah.
The quality of Dee Henderson's books/writing appear to have gone drastically downhill since her O'Malley series. I'm not sure I want to even bother checking out any forthcoming works.
Really pathetic and not worth the read.

I tried reading Undetected when it was in my Library's catalog (don't know if it's still there) and I just couldn't get into it. So about a year ago, the ebook was on sale and so I bought it...I really liked Undetected, just didn't care for all the technical stuff that flew over my head. When Dee Henderson writes her characters they are brutally honest, there's no wondering about them. What you read is what you get. It's an honesty that I don't typically see in a lot of stuff I read and it's refreshing.

This was an enjoyable read. I know many have bemoaned the loss of the O'Malleys. That was a special series. I love that in Undetected it had twinges of a Clancy novel without getting bogged down in the nitty-gritty details. This book has an edge of thriller to it, and a slice of romance. It's not your typical romance because the heroine has to grow into love, but I enjoyed the way it was different from the typical romances that are available.

Ever since seeing The Hunt for Red October I've enjoyed submarine stories. This book is thick with technical information that still reads smoothly along with the plot and characters. I appreciated that the men in Gina's life encouraged and supported her in her inventions and endeavors instead of being intimidated or competitive like some boyfriends in her past. She has two great guys to choose between, and it didn't seem quite realistic how easygoing they were about that. The tension comes as she keeps developing technology that gives the US an advantage at sea, but the powers that be understand that it will become dangerous when espionage makes it available to the enemy as well. Mark helps her keep things in perspective, that her talents should not be suppressed but built upon. The pace is somewhat slow but steady with not much suspense until the very end, when the culmination of her projects are used in a way nobody could foresee. The romance was a bit tepid with Gina's insecurity, resistance, and indecision, definitely a slow burn.

If you enjoy submarines, sonar, romance and off the chart gifted intelligence (or even if you don’t) Undetected can satisfy. Dee Henderson has such a way with words, with people and dialog. And her research? Unmatched. I have no idea if all the sonar theories or underwater tests explained in this book are even plausible, but my, was it fascinating.

I've never cracked a book about submarines and I wasn’t even sure I’d like it. Most of my brothers were in the Navy, so I was interested, but we're all claustrophobic so submarines are scary. Getting beyond that and focusing on the story was a delight. More than you’d ever want to know about submarines and solar flares, but it all just fit.



Characters: I liked Gina, and I really liked Daniel. I liked a lot about Mark, especially his relationship with the Lord, just wish he had been less pushy.

This book followed two other books about damaged women. In Undetected, Gina's perhaps cautious with her heart, but not damaged, per se. She's gifted beyond belief. Started college at fourteen, earned six advanced degrees and at twenty-one her first PhD. It was nice to read about such a brilliant yet sensitive woman.

Good book. Perhaps not the fast pace and suspenseful sort the O’Malley books were, but I felt like Dee Henderson was back and she did a nice job.

Dee Henderson is probably my all time favorite author and whenever a new book of hers is out I get so excited! Undetected was just as brilliant as all of her other books but it was also new and exciting with a whole new background: submarines!

I love it when an author continues in their writing style that us readers have come to love but also continues to find ways to write intriguing stories without writing the same old story over and over. Henderson never disappoints.

You can certainly read Undetected as a stand alone novel but I would suggest reading Unspoken first.

Undetected is an amazing story of a woman, Gina, who fairly effortlessly keeps coming up with ways to help the Navy keep their submariners safer...mostly because that is what her brother does and she wants to keep him safe. She is brilliant but also a workaholic. She knows the research and development she works on will save lives so she has a hard time taking a break.

Meanwhile her brother's best friend, Mark, is also a submariner and just happens to be the first person Gina tells about her latest research. He agrees to help her get subs underwater to help her test her theories before he leaves for his next submerged patrol.

Just like all other Dee Henderson books you don't really wonder who will end up with who but she sure does keep you guessing as to the when and how of the relationship. This book kept you guessing in that area more than some of her others and I loved it. I am also thrilled that yet again she seamlessly included strong personal relationships with Christ in her characters. She also always includes a lot of prayer times for her characters. You cannot read this book without knowing that Dee desires all people to grow closer to God and also strengthen their prayer lives.

This book is perfect for you if you enjoy romance, suspense, or military fiction.

I wanted to love this book. I’ve read Dee Henderson’s O’Malley series years ago and loved them all. So when I saw her name on Undetected, I couldn’t wait to get into it. However, as I slogged through paragraph after paragraph of fine detail about submarines and their workings, I had to wonder. Was this really written by a woman? It felt like a man’s writing to me. Very analytical with emphasis on settings rather than characters. The author’s in-depth research impressed me, as I assume her descriptions of submarine life are correct. The plot was laid out well, despite what I thought was too many unnecessary details. The only tense scene was tense enough. The male characters were honorable gentlemen, even while courting the same woman. And while I could not identify with Gina’s genius, I did identify with her social insecurity.
But as a romantic suspense, it disappointed me. So with a heavy heart, I give Undetected three stars. I was given an e-copy of this book in exchange for my honest opinion.

Dee Henderson is one of my all time favorite authors, so any book she writes is automatically on my TBR list. I eagerly awaited Undetected and while I liked the book , I did not love it. Undetected is about Gina Gray, a genius sonar scientist and Mark Bishop, submarine commander and brother of Bryce Bishop from Unspoken.
I loved their romance, but feel the story lacked Dee's usual suspense. She seems to be going in a new direction with her books. If the book had been by a new author I think I would have enjoyed it more. I will probably read it again without the expectation of suspense and thereby enjoy the characters.
I believe once I get used to Dee's new style, I will look forward to reading her books with just as much anticipation as always.
My advice is to read Undetected with an open mind.

I loved this story! It is my favorite of Dee Henderson's newest set. I really enjoyed the description of life aboard a sub, especially one that carries nuclear weapons. The two main characters were interesting & had some good discussions that I enjoyed reading. I also found the sonar ideas Gina came up with very intriguing.

Undetected by Dee Henderson kept me glued to its pages until I finished it. What a book! I’ve loved all the books Dee Henderson has written from her O’Malley series to this newest series which links back to characters from other beloved books. After reading Undetected, I discovered Henderson had written another book, Unspoken, which leads me to hope there’s a new series in the works. Somehow I’d missed Unspoken, so went back to read that one right after finishing Undetected. Quite honestly, I’m hoping there are many more “Uns” to come!

Set in beautiful Bangor, Washington, on the Navy base there, “undetected” refers to the nuclear submarines of the U.S. fleet and their mission to cruise undetected through all sorts of waters. The hero of the story is Commander Mark Bishop, of the U.S.S. Nevada, a “boomer” with an exemplary record. I was fascinated by all the submarine lore as well as the running of the sub’s mission. The heroine is Gina Gray, a brilliant mathematician with a bad record of relationships who moves from Colorado after a bad break-up to Bangor where her brother, Jeff, is stationed as C.O. of the Skywolf, a fast tactical sub.

Because I am “math-challenged” I found Gina’s talents a bit hard to believe, but found her very believable. I found myself rooting for her and wondering what she would do next. Deciding she had done a rotten job of finding a guy for herself, she asks Jeff to set her up with a “good” man. Jeff’s first choice is Bishop, but Mark takes himself out of the mix because he feels he is too old for her.

’nuff said. You’re going to have to read the book to find out the rest. I guarantee you will have a much greater appreciation for our submarine forces after you finish the book. And you’ll be hooked on Henderson’s writing if you’re not already.

In Dee Henderson’s Undetected, Mark Bishop loves his job as the commander of the U.S.S. Nevada, a submarine on the front lines of America’s defense. And he is good at his job. But when his tour of duty ends, he would like to have someone waiting for him at home….

Gina Gray is on the rebound again. Her dream of marriage seems farther from reality as her latest relationship has fallen through and she is left to pick up the pieces…alone. Too smart for her own good, she is on the verge of a discovery that could revolutionize warfare, but she needs help before it turns her world upside down. Will she get it? And will she ever find someone who loves her for who she really is?

This book had potential. Within the first few pages, the settings are wonderfully described. The reader can see the beauty of Washington State in the mind’s eye, and the technical knowledge of submarines and solar flares is impressive.

However, the rest of the book came up woefully short. Neither character matured or changed. One would think Mark, a military man, would be more masculine and reserved. However, he is annoying and unrealistic. He speaks too freely about his feelings to those under him. In his relationship with Gina, Mark is syrupy, emotive, and condescending. Rather than being chivalrous, he is pushy and preachy in places.

The plot line is poorly constructed and predictable. The romantic angle is overplayed, and there is not enough military suspense. Undetected is hard to get through, and, unfortunately, I cannot recommend it. I have read better books by Dee Henderson and look forward to more in the future.

MY THOUGHTS ON THIS BOOK 

I have never read a book about submarines so I was really glad to get this one to read. And I love, love Dee Henderson’s books, all of them to date, so I knew this has to be an awesome read. And for me it was. I loved reading all of the technical stuff she so expertly added to her story. Reading a few reviews, I understand a lot if people didn’t care for the detailed info, but that is just Dee Henderson at her best. I will admit, I went back and read some if the scenes again, or some more than twice, but I still found it so interesting and intriguing. And I am so happy for all of the submarine talk to learning about them. It is a new topic for me and I really enjoyed it all.

The characters were well and perfectly created, and their development throughout the story was amazing. I love Gina, and Mark too! And was glad he was there for Gina. He was just the right person to give her the stability she needed. Gina was a genius, and I loved her part in the story and loved how the author shows that even though a genius person like Gina has everyday struggles just as the rest of us. Ms. Henderson does an amazing job weaving this into the story. And as for Gina and Mark’s attraction to each other, I love the romance!! Romantic and suspenseful! This makes for a story that will stay with you for a while.

If suspense and thrills are what you are looking for in a book, check this one out. I know it’s been out for a few years but it’s still the amazing book it was when released!

A special thanks to the author/publisher for a copy of this book. I am not required to write a positive review, the opinions here are mine alone. I am disclosing this with my review in accordance with the Federal Trade Commission’s 16 CFR, Part 255.

This book was AMAZING! I was impressed with the research Ms. Henderson must have done to accurately portray the background information for this story, including submarine techniques, procedures and language. Her research confirming facts surrounding our national defense, protocol in the event of nuclear threats, and proactive techniques that would stay on top of the defense for our nation was unequaled.

What I loved: Seeing into the minds and emotions of the characters made them come alive. They had authentic struggles for their personality traits that made their emotional reactions believable. As a reader, I sympathized with each struggle and cheered for the outcome. And, of course, I enjoyed the romantic sub-plot and the uncertainty of whether Mark and Gina would end up together in spite of the difference in their ages.

What I didn’t like: The book was somewhat long and mildly echoed some aspects of the plot. Although the technical descriptions were accurate, sometimes they almost bogged the story down and took away the light feeling a person craves when reading a book for pure enjoyment.

Ultimately, I loved this book. If I could give it more than five stars, I would. Anyone connected with the military, particularly the Navy, would enjoy reading “Undetected.” However, I’m convinced anyone serving in any branch of the service or connected with someone serving would also love and appreciate the discipline and military structure portrayed by the characters. On the other hand, I have no connection with the military, and I loved it anyway. I highly recommend this book to anyone.

There is something about Dee Henderson's writing that I both love and love to hate.

Love: She writes a richly detailed contemporary romance that is neither hot and heavy, nor solely focused on the romance. Her characters live full, "interesting" lives as they develop a relationship and fall in love.

Undetected is no exception. Gina is a strong female character who makes ground breaking scientific discoveries as easily as the rest of us eat breakfast. Mark is a protective male with a fulfilling Naval career on a nuclear submarine. The reader learns a lot about day-to-day operations on such a submarine. Over the course of the book, Gina makes several discoveries that both draw the two together and affect Mark's working life.

Irritants: Words are over used. How many things were "interesting" and how many times were things "offered"? Plus, Mark is entrusted with part of the launch code for nuclear weapons, but his brother won't initially tell him who Charlotte is? Come on.

Having read her other titles, I expected there to be more of a suspense element than there was, but it was still an enjoyable story.

Totally recommend !!
Settings: Bangor, WA and Chicago.

2nd read thru on 8/1/20 for book club.
The first half had me glued .. but it does bog down a bit after that. Maybe more editing for that bit to keep the pace up?
I really liked “Genius Gina” and Mark Bishop.
Jeff and Daniel are excellent secondary characters.
Wonderful ending.
Solid top rating. I want to read it again.

Very good as most of hers are. I feel like I’ve learned quite a lot to do with submarines now. I am fit to command one 100%. At first I was a bit confused on a turn she did but she did it so well I had to accept it. All in all kind of a slow book but good.

Dee Henderson brings us a wonderful romance that centers around the Navy, in particular the submariners. The story was slow for me at first because of all the background give about submarines, but as the story progresses you quickly see the necessity. I learned many things about submarines that I never imagined.

This story also shows us that at all times we need to trust in the Lord and seek his guidance in all things.

We are introduced to two incredibly strong, well developed characters. Commander Mark Bishop commands the USS Nevada, a ballistic missile submarine, which goes out on 90 day submerged patrols. There were two constants in his life, the Navy and God. Mark is a widower and after many years now yearns for someone to come home to. Looking for a wife was easy, but finding one to fit into the navy culture would be the difficult part.

To say Gina Gray is an exceptional woman would be an understatement to say the least. She is one scary smart lady, but has always had difficulty fitting in socially. She has always dreamed of finding a normal life. She started college at the age of 14 and a normal life always seemed to be just out of her grasp. She has always had an interest in ocean science research and while in college developed the cross sonar technique for submarines. Recently she has been working on sea bed mapping using satellite data, but after an unexpected breakup with her boyfriend of 2 years she feels a change in environment is necessary. She leaves Colorado for the Bangor area in the northwest part of Washington State. Her brother, Jeff, a commander of the USS Seawolf lives there and she really likes the area. While there waiting for Jeff to return from his 90 day patrol she borrowed a lab so she can work on some ideas.

Mark exhibits characteristics anyone can appreciate and love. He is always trying to do the right thing, protective, honest to a fault and his faith is unshakeable. Gina on the other hand appears very insecure about many things, but as you get to know this character her gentle strength comes to light.

The plot of this story is very intriguing. It has some mild suspense, but is mostly about the gradual build of a relationship between two people. The imagery the author uses brings the ocean alive to the reader. Her true to life dialogue will pull the reader in.

One scene of the story pulled at me more than any others. Gina is telling Mark she doesn't understand military life and how with his faith he could on command from the president release nuclear weapons knowing he would be killing so many people. His explanation was long and involved, but he tells her....

"God made a world that was all good, but because He also gave people free will, the potential for evil was there from the beginning. God didn't make evil, but He allowed for the possibility.

To me that passage says a lot and answers the questions of why God allows evil to happen in the world.



I would recommend this book to anyone, because not only is it an enjoyable read, but it will also spiritually touch the reader.

Since Dee Henderson’s return her books have been very heady and lengthy. This book is no exception, however, unlike the previous one that focused a great deal on coin collections this one looks at topics that a broader audience would enjoy.

I loved Gina Gray as the brilliant expert on sonar technology. She has a sweet almost innocent personality but she also had a sassy side as she interacted with Mark Bishop. Throughout most of the story I really liked his character, although there was a section about halfway through the book I felt like he was a little aggressive in his relationship with Gina. Even with that overall he was a great character.

I enjoyed the storyline with the different technologies discussed in regards to the submarines and war tactics. I would love to know how much of the science described in the story is feasible. The romance was well done and had an interesting aspect to it that I don’t think I’ve seen before.

Each of the characters grew in their faith and a deeper understanding of what it means to trust God.

This is my favorite Henderson book since her return and would recommend it to those who have enjoyed previous Henderson’s books or if you enjoy books that focus around the Navy and Naval ships.

I grew up watching Glenn Ford and Clark Gable command submarines. I loved those sub movies. so when I saw this was about a nuclear sub commander, I had to read it.

And I loved all the sub life. I have no idea if the world of the submariner was represented accurately by the author. It felt accurate. I really liked the characters and the plot.

The book is an inspirational romance. I read a fair sampling of these, but found this one different. The book goes all the way through a relationship. They fall in love, they get married. But there isn't one tiny spark of physical/sexual chemistry between the couple. I mean, none. They think about being in love, say they're in love, even kiss, but they never have a single physical manifestation of feeling love, of being attracted, of feeling desire.

This is just how this author does it. And I guess her readers like the story told that way. I'd like a little sexual tension thrown in there. For me, it would have taken the book to a whole 'nother level.

I did enjoy the book, though. It made me want to search for more submariner books!

Wow, I feel like I just completed a crash course on the Navy and how it functions. I can't imagine the amount of research the Dee had to do to give us so much concise details. It was fascinating to learn about the in and outs of a ballistic missile submarine. I just wish Dee had a note, like Dan Brown puts in the front of his books (especially his early science books dealing with NASA and the NSA), telling us what's factual in ocean science research. Because now I want to know if the Navy really has all these capabilities and uses them.
Anyway, I loved the story and I love Gina..."Gina, the genius". And she is a genus, in that she can figure out things that other people can't, but once expressed, they are simple and easy for others to grasp and understand. Her ideas are beautiful in their simplicity.

Mark Bishop submarine commander and Gina the genius Gray have known each other for years through her brother, his fellow Naval officer. She is fresh off a breakup but so badly wants to be married. Mark is a widower finally deciding to move in. He was a good husband and wants to be a husband again.

This could have been a great story but it was just too 'odd' for me. It's a Christian romance so it is beyond clean. This book, compared to others in the series is a lot more religion based but that's not the problem I have with it.

The chemistry is non-existent. It's not love but best case scenario. I think Bishop may brow-beat Gina into marrying him and falling in love with him.

This book was full of way too much technical stuff. She definitely did her research on the subjects at hand but it was presented in a how to format. I may not be a genius but it was all way beyond over my head.

I don't think there has been a Dee Henderson book I've not enjoyed. That being said, this book had a lot of details about the Navy and submarines. While they were interesting and pertinent to the story, I felt like it got to be a bit much sometimes. However, it was interesting the genius things the book had Gina discovering like the info from the solar flares. :)
I didn't care for the way Bishop put so much pressure on Gina to just up and marry him. There was a little too much of the attitude that he knew best and she was too young to understand. I like the way she stood up to him though on that issue and like most of Henderson's couples, I love their relationship in the end.

Fascinating! Dee Henderson has definitely recalibrated her writing style somewhat, but "Undetected" was an intrinsically interesting read. I loved the gentle pace, I loved learning more about our Navy, I loved the depth of characters and their quality conversations and most of all I loved how Gina allowed her fears to subside enough to genuinely open her heart. And those letters! Who wouldn't want to receive one of those! Open the pages of "Undetected"; it's a book to savor; like a fine dessert.

Finally done with this slooooowwwww book. I agree with the other reviewer who said Dee Henderson must've been abducted by aliens. This book has really no suspense, and no passion in the love relationship. It's more of a convenience than a love story. The story was okay, and interesting at times, but definitely didn't qualify as suspense. Gina and the "smartest girl in the world" routine got really old after awhile. And that ridiculous "speech freeze" problem - ugh. 2.5 stars.
