I really liked this book,the writing style, the plot, the characters. I'd never heard of this author before but I will definitely be reading more of hers work.

Sarah Armstrong was a profiler with the Texas Rangers. A single mother whose husband, Bill, died in a car accident, she's worked hard to prove herself while supporting her daughter, Maggie. When a wealthy man is murdered, along with his mistress, suspicion quickly falls on the estranged wife who had means and motive. However, Sarah feels d

PROTAGONIST: Sarah Armstrong, Texas Ranger
RATING: 2.25
WHY: Sarah Armstrong is one of only two female Texas Rangers on the job. She's on a case involving a psychopathic serial killer, and is the only one who doesn't believe the prevailing profile of the murderer. Although not badly written, I ended up disliking this book a lot. She exhibited the most appalling personal and professional judgment. Every time she made one of these bad decisions, I felt my gut churning - it

I obtained this free e-book from Amazon and I am voluntarily writing a review. Wow. This is the first that I have read of this author and I am hooked. Sarah is a Texas Ranger Profiler, recently widowed with a eleven year old daughter and they are living with her mother on a small ranch in Texas. She is called on a high profile double murder case of a wealthy real estate tycoon and his lover. The murder reeks of a ritualistic, fanatical religious serial killer but with the killer being meticulous ...more
That might be one of the worst "thrillers" I've ever read......Ever.
There were complete story lines that were totally abandoned. But all the hack, corny, cliche',cheesy, parts of a typical "thriller" were all there. And, boy they were there very bigly as President Trump would say.

Now, apparently, Kathryn Casey writes True Crime books also. I'm a fan of the True Crime, so I can't say I'll never read a K Casey book again, but I can say with 99% certainty that I'll never read a Sarah Armstrong nov

A story of a female Texas Ranger who is widowed and has a young daughter. She is a profiler and is chasing a serial killer. Starts out fast paced and follows through to the end. A very good, quick read.

Ehh, not the best thriller I've ever read. Too many one-dimensional characters, lack of continuity in certain spots, writing was only so-so. IF there's another in the series, I probably will not read it.

Have you ever gotten halfway through a movie, realized you don’t care what happens, but yet, still keep watching just to see how it ends? That’s how I felt with “Singularity.”

This was the first novel I’ve read by this author. I highly doubt there’ll be a second.
The book was mildly interesting. It was readable. Didn’t drag, wasn’t overly descriptive. It passed a few nights and really, isn’t that what a novel is supposed to do? That’s about the only positive I have. It was better than watching mi
I enjoyed it, but a bit unbelievable near the end.

Sarah Armstrong is a profiler for the Texas Rangers, one of only two female Rangers. She gets a call one morning to go to Galveston to view the bodies of a prominent business man and his mistress. Sarah suspects a serial killer, but the Galveston P.D. arrests the man's widow. Sarah pursues her leads with the assistance of an F.B.I. agent. The denouement was completely predictable, but I enjoyed the relationships between all the characters. I like Sarah and her daughter, Maggie, who are strugglin ...more

Ok, I didn't read the whole thing but that's because I like actual mysteries--the room full of suspects while the detective (amateur or pro) deconstructs the case and lays out the facts pointing to!--so these police serial killer forensics hoo-hahs bore me to tears. Screw thrillers and suspense stories, I like a knotty mystery to try and unravel. This book just screams "I found a niche nobody has done yet so i will write a typical serial killer book with it"--she's a Texas Ranger! that's right!

This book was fun and fast to read. The characters are one-dimensional and the plot is entirely predictable. Even with those strikes against it this was a decent book. I don't regret reading it.

Gripping Serial Murder Mystery!

Texas Ranger Sarah Armstrong has two strikes against her. She's a female ranger in a traditionally "man's world," and a "profiler" to boot. While her boss seems to trust and respect her, the "good old boys" she has to work with are not so accepting of her presence or her expertise. When a wealthy local man and his mistress are found murdered at his beach house, this gender bias blinds the local police. They ignore Sarah's professional opinions, and some pertinent f

Sarah Armstrong is a texas ranger and she really enjoys her job but the last year has been really hard on her & her daughter Maggie as her husband was killed in a car accident and they are both battling. Sarah knows that her Mom is being a great help but it is still hard as she can't be both parents no matter how hard she tries. She has been given a new case but not everyone is on board with her idea that the murder could be the work of a serial killer. She hopes that she is given time to fi ...more

"Singularity" is a solid, engaging read. While the police and forensic procedures are a bit condensed time-wise, they are for the most part very accurate. The main characters are interesting and likable, though the secondary villains are not nearly so well rounded, and tend to play one unsupported note. The plot proceeds nicely, with sufficient discoveries along the way to keep the reader's interest. Aside from the unimaginative characterizations of the secondary villains, I found the greatest w ...more

I am not a fan of the serial killer genre, so the fact that I read this rapidly and enjoyed it should tell you something. Sarah Armstrong is a character with possibilities, and her household consisting of a loving mother and a teenage girl who's willing to believe totally inconsistent ideas from one day to the next (like most young teenagers I know) warmed my heart. Although my wife pointed out a plot hole--(view spoiler) ...more

First novel in a series that is promising. We meet Sarah, who is entirely competent yet not cocky, in how she is is navigating her professional and personal life. She is handling things, but it isn't easy and she questions herself. She has enemies in the various departments she interacts with, she is a widow with a preteen child, she has a high profile case, she has a hunky temporary partner (of course!), and there's a serial killer on the loose, too.
The home story line is well drawn, the police

Indeed singular

There aren't many books about modern Texas rangers, I haven't seen even one before this about a woman ranger and I loved it. Smart, well thought out, different, and from HOME in all the best ways. Sarah Armstrong does come across as real, her livelihood and life are real, and it is a pleasure to read a mystery that requires more than just logic to solve. One has to believe in the reality of the place and the characters to solve the crime, or even just hang in there and follow Sara

He’s on a mission from God...

At least that’s what the stealthy serial killer who’s caught the attention of Texas Ranger Lt. Sarah Armstrong following the murder of a rich Houston businessman and his lover.The Lt. has a problem,no one wants to believe there’s a serial crisscrossing Texas hunting down victims. But when the killer threatens her loved ones she’s like a momma bear protecting her cubs and the killer is not long for this world.
I’m looking forward to reading more about this Ranger.

I’ll Read More

Despite a few minor proofreading mistakes, and formatting in the kindle version that made conversations difficult to follow at times, I enjoyed this book. Likable characters, a plot that surprised me a couple of times, and an ending that ended the story. Books in a series can leave me uneasy when you have to read the next one to fully “get” the previous one. This was a complete story and I appreciated that. There are hints of what will come, but nothing that leaves an unsatisfied f

This book was a break from my normal genres and it was absolutely amazing. Great story telling and visuals.
I live in Texas so part of this story was right in my backyard. I learned a few things about Texas Rangers and in look forward to more in this series.
I loved Sarah & Maggie & Strings. I’m glad the story didn’t have a cliffhanger.

Debbie did an excellent job narrating. This was the first book I’ve listened to by her.

Interesting who done it

This is the first book I read by this author and I was intrigued. The story line held my attention and I enjoyed the strong female lead. Sarah the female lead was fighting against old boy staunch sabotage of the case she was chasing and a very singular minded killer. Throw in some odd things like two wealth families fighting over custody of children and you get a lot of intrigue.

I will look forward to reading more by this author in the future.

A Texas Ranger Profiler/An FYI Profiler/A Psychotic Serial Killer

KC has penned a murder mystery that included a Texas Ranger profiler, an FYI Profiler and a Texas Ranger charlatans herein the back because she was right in her conclusions that they were after a serial killer rather than a rich widow. The female Ranger is forced to overcome the hard liners who are against a western woman ranger. This is an excellent read for the genre.....DEHS

This is the first in a series featuring Texas Ranger, Sarah Armstrong. Sarah has recently been widowed and is raising a young daughter with the help of her mother. As a Ranger, she is investigating a dual murder that she realizes is more complicated than a simple murder by wife. Working with the FBI and others, she soon realizes they are hunting a serial killer whose murders have religious overtones.

Clever and absorbing

This well written tale is fast paced and cleverly plotted. Peopled with well-rounded, authentic voices and peppered with historically interesting facts about the places they inhabit, there's a rich tapestry woven around this story that is beguiling. The author has a talent for creating atmosphere which keeps the reader enthralled. I thoroughly enjoyed the telling of it, and the nicely sharpened end to it. Highly recommended, and kudos to the author.

My first read/listen from author Kathryn Casey. A well-written book with captivating, well-developed characters. Narrator Debbie Andreen’s talented narration adds greatly to the book’s enjoyment. I was given an Audible copy of this book & am voluntarily reviewing it. I’ll be reading more in this series, in fact when I'm done with this review I'm going Amazon shopping.

Yes, this is the tc writer. She wrote this fictional book.

Sarah is in law enforcement. They are looking for a serial killer, who seems to be one step ahead of them. With help, from other law enforcement, including the FBI, they go on the hunt. There are other people involved also. Her daughter and her Mom. Neighbors round out the cast of characters. Book two, is out now.

Texas Ranger comes into the 20th century

Wow! What a book. We meet Sarah, one of the few women Texas Rangers. The character is incredibly well developed . The plot has twists and turns that make it impossible to put down. When I completed this book, I had to immediately buy the second in the series. An excellent read

I see a lot of reviews that are 2s and 3s. But to me I gave this book a 5 because it is one of those books that has a little bit of mystery, fun, junk and everything to keep you reading. If you want strictly a cold mystery thriller with no smiles then this book is not for you. But if you want a book that you read clear to the end and how you couldn't put it down, then this book's for you.
