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

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 fel

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 peo
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."

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 wo

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 descri ...more

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

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.

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.

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 discover
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

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 Na

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 ...more

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.

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 f

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 ...more

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 n

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.

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

I enjoyed this for the most part. I had already resigned myself to the fact that the story would probably be boring and not too exciting, gaging from her other similar releases, but I found this to be comforting. Was it too long? Probably. Did I really need to know all about submarines? Probably not. But I knew that going in and settled in for a comforting read, and this delivered.

I loved reading this book! The fascinating life of a navy commander, a sweet love story, and the intrigue of everything happening... this book was a very enjoyable read!
The one thing I didn't care for, was the laid back dating relationships and a some-what careless approach to male and female relationships. That is the biggest thing I didn't like.
I did get lost in all the Navy and scientific terms but I still for the gist of everything happening! Oh, and I love how Mark pursued Gina... even if

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. Command

UNDECTED by Dee Henderson might’ve had a few flaws, but I still had a hard time putting it down.

Gina Gray is a genius. A gift she has struggled with her entire life. Socially awkward, Gina has a tendency to put too much pressure on herself, causing her to freeze up in stressful situations. After yet another failed relationship, Gina decides to go to her brother’s and await his return from sea.

ABOUT THE BOOK(in my own words):

For me, the title and cover of Dee Henderson's book "Undetected" are misleading. I was expecting a suspense-filled, action-packed novel, and this book did not meet my expectations. Actually, the book almost seems like two separate books that are merged into one. One part of the book reads like a guidebook to life on a submarine, filled with technological jargon and Navy terminology. The other half is a romance. Suspense and mystery really don't play a role in this book.

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

Dee Henderson's later books don't sparkle like the O'Malleys & Uncommon Heroes Series but I did end up getting really drawn into this one.

What I liked:
~ Both were Christians to start with.
~ Gina was different due to being a genius, and while it stopped mainly relationships, the hero applauded and encouraged her differences. He made her feel special.
~ The way the hero pursued, protected and loved her was very sweet.

Undetected by Dee Henderson is a fresh and fascinating tale of life as a submariner for Mark Bishop and life as a genius for Gina. If the name Bishop sounds familiar is it.  Mark’s brother is Bryce from Unspoken.Undetected is full of details about the submariner life and Gina’s discoveries. These details may overwhelm some readers.  If so, I recommend you skim them and stay with Gina and Mark’s stories; it is worth it.  Mark beautifully tries to woo Gina with letters and conversation.  My favori ...more

“Please understand something. God didn’t create evil in the world, but He did create free will, which allowed for the possibility of evil. Science isn’t like that. What you explore and find, God did create. It already exists. When you find it, you are discovering something God made. And everything God created is good. God said so in Genesis. He looked around at everything He had made and said, ‘It is very good.’”
“How men use science can be evil, I’m with you a hundred percent on that,” Bishop added. “People can misuse items God created.
