A well-crafted suspenseful thriller with perfect pacing...

Fatal Decision: A Sam Harker Thriller by T.K. Wolf is a wonderfully written and richly descriptive novel with brilliantly drawn characters and settings. The threads of storytelling are expertly woven in this high-octane thriller that will guarantee the attention of the reader. A skillfully constructed action-packed thriller, this book will have you turning the pages from beginning to end. In addition, the characters are drawn with great credibility and conviction.

The book description gives a sneak preview: ‘A killer who lurks in the shadows striking out at those who created her… Sam Harker’s life as a highly-skilled assassin was forced on her by Delphi Intelligence, the multinational corporation who controlled her life for years. After escaping, Sam has played a deadly cat-and-mouse game against her former employers… To save the man she loves; a killer must tap into the darkest parts of her personality… However, when her past catches up with her and spills over into the new life she is trying to create, Sam must return to finish one last job for Delphi… Unsure who to trust or what to expect, Sam must do whatever it takes to keep Jake safe. Even if it means destroying herself in the process… From Mexico to New York City, she faces a seemingly impossible task while navigating the complex web of secrets and factions. With no guarantee of survival, Sam must use every ounce of her skill to tip the odds in her favor… A single decision can have deadly consequences.’

I enjoyed the story, character development, and dialogue. There were plenty of plot twists that I didn’t see coming and that added to the book’s mystique. When I stopped reading to work, I found myself wondering what happened in the book, and replaying parts of the story in my head to see if I could figure more out. It has been a while since I enjoyed a book this much. It’s a well written suspenseful thriller with perfect pacing. Highly recommended.

Sexy, Confident and Smart Hero in Equally Engaging Spy Thriller

Fatal Decision by T.K. Wolf is an exceptional spy thriller that features the most deadly of all killers. A beautiful, sophisticated, engaging, glamorous femme fatale by the name of Sam. She has the ability to lure, men in particular, to their demise and leaves them wondering what had ever happened.

That killer was once a successful skilled member of an organization known as Delphi. This disreputable organization utilized sophisticated computer software. The primary purpose of utilizing the software was to gather information on powerful people to sell that information to the highest bidder; information that could be utilized to control that individual and keep them strongly within the grip of Delphi. Their reach was far and wide and deep.

Sam left Delphi. However, Delphi did not have an exit plan for their former employees or soon to be former employees. The exit plan was termination not only of their involvement with the organization but their life.

So Sam takes it upon herself to utilize her complete skills, expertise, and female wiles against her former employer and become a real problem for the organization. She wanted to make them suffer for the crimes that they had committed in their quest for domination.

The opening chapter immediately captures the reader's attention and fully immerses the reader with the beginnings of a well-developed novel and spy thriller. Sam's personality is well-developed as she personifies the sexy but more importantly excellent spy bent on seeking revenge.

The novel is sophisticated, entertaining, and perfect on developing the main character's personality and in the description of her actions and her ability to wreak havoc. T.K. Wolf has gifted the reader with an excellent spy thriller. The book is action-packed, entertaining, and is sure to glue the reader and their imagination from start to finish.

A gripping tale of mystery and intrigue as an ex-operative turns against a secret and evil organization.

Sam was identified by a secret and a malicious organization known as Delphi, when she was a young woman, as a superb candidate to train as an agent and an assassin to execute secret covert missions for them. Proving more than adequate for this task, she excels and becomes one of their top and most trusted operatives. But all along, she knows that she will leave them one day, and she secretly accumulates stolen funds and information about their vast connections and capabilities. Realizing that she cannot continue with this line of work for too long, she is also thirsty for revenge about how they recruited her. When the time is right, she leaves them and also manages to conduct some private missions of her own, even though the powerful organization is determined to track her down and capture or eliminate her. Despite the odds stacked against her, she manages to evade them successfully but then she makes a fatal mistake that operatives should never make. She falls in love and meets with her lover regularly. This exposes the chink in her armour as they track her and her lover down, using all the resources at their disposal. Sam has to rely on her accumulation of contacts and resources to save them both. However, she has destroyed his life in the process and they both may certainly be trapped and killed or captured. She has some difficult choices to make, as this dramatic plot unfolds and agents of the ruthless Delphi organization are determined to find them both. This is a masterfully written thriller, with detailed pieces of information, as well as an action that is convincing and realistic. The pace is fast and relentless, with action-packed sequences and thrilling suspense that makes this an entertaining and superbly thrilling reading experience.

A seductive, action-packed thriller that has a stiletto-clad foot on the gas for the entire ride!

In T.K. Wolf’s debut novel, a career assassin gets recruited for one last job with the shadow organization she had escaped.

After finally slipping free from Delphi, the multinational shadow organization that molded Harker into a highly skilled, one-woman killing machine as a young woman, Sam Harker has turned vigilante and set her sights on disrupting Delphi’s international network of unsavory informants.

But her methods have proved far too effective and disruptive for the organization. Soon they force her into a final job that threatens the one real connection she has made since being orphaned at 16 and eventually recruited by Delphi. Harker is forced to tap into her dark past and unconventional profession to save the man she loves.

In Harker, Wolf has crafted a female assassin that Robert Ludlum fans can heartily embrace, complete with a familiar recruitment origin story. But unlike Jason Bourne, Harker has a full arsenal of deadly feminine wiles in her kill bag and she’s not afraid to use them — whether that means infiltrating a notorious drug cartel or slowly and methodically prying out information from human traffickers.

Wolf’s pacing is just right, delivering actions and insights in potent doses, with just enough backstory and character development to give the novel sufficient heft. And thanks to sharp prose, Wolf takes us from Mexico City to Manhattan with a rapid-fire delivery that achieves pandemic-era pleasure.

I enjoyed this Read!!

Tim K. Wolf's three-hundred and thirty-six paged book titled Fatal Decision, bothers on love and survival, which one would you choose? Sam is described as extremely sexy, flirty and when she is on an assassin's mission to exert vengeance on her former employers. I asked myself, what is it with Mexico and cartels and crimes?

This story is definitely entertaining to read through it sends shivers down your spine sometimes if you have witnessed less violence in your life. When Sam says “If you don’t start talking, I am going to use this scalpel to take out your eye. One.” I thought she was bluffing and was stunned in the manner she carried out her operation. I found it to be extremely entertaining and thrilling, there is a huge tease with the imagery of intimacy and wild romantic "sex-capades".

This story has a fine twist of blood and death and an impeccable development of the central character from her earlier weakness to gaining strength and overcoming her challenges. I pondered how the author came from such knowledge and wasn’t surprised to have learned that Tim Wolf is a former army brat.

For lovers of cold-blooded killings with a blend of romance, Wolf's book definitely goes a long way to whet that appetite.

Fatal Decision is an amazing thriller! The author, T.K. Wolf created a really gripping story full of spicy ingredients such as action, mystery and love which kept my attention the full time.

The plot of this book focuses on Sam, a highly-skilled assassin who used to be part of an organization, Delphi. Sam wasn’t happy working for them because of what they had done to her, what they forced her to become and the unmentionable atrocities they have committed in the quest for more power and money. So, she left Delphi but the penalty for leaving them is death. Now, she must play a deadly game of hide and seek while trying to save the man she loves.

What attracted me the most about this book is that the main character is a powerful woman with strong beliefs, who is determined and self-confident. Personally, I felt very identified with her and her story which is well written and full of journeys, twists and challenges.

All in all, this novel is a great partner for these days. You won’t regret it. I highly recommend it!

Fatal Decision is a very interesting thriller and the debut novel of the author T. K. Wolf. It is a quick and fascinating read listed as science fiction, it is no different from others I have read, but it has unique features of imagination, with a really good plot and really complete and descriptive characters and scenes.
Sam Harker, the protagonist of this story, is a highly-skilled assassin who has to save the man she loves, but a single decision can change everything and she is about to discover it.
From the very beginning, this book had me hooked and I found myself reading compulsively its 334 pages. As soon as the readers open the book, they will find an amazing battle, bloody moments, mystery, intrigue, passion and a lot of action which makes the story very interesting and entertaining.
When I opened the book, I thought that it will be difficult for me to keep the focus on so many chapters, 30 exactly, but they are so absorbent that it motivated me to finish it as soon as possible.
I really enjoyed reading this masterpiece, I absolutely recommend it.

Fatal Decision: A Sam Harker Thriller is a gripping, adrenaline driven story that blends emotional depth with high stakes action. T.K. Wolf masterfully crafts a heroine readers can’t turn away from Sam Harker is fierce, skilled, and emotionally complex.

The novel follows Sam as she attempts to build a normal life after breaking free from a manipulative private intelligence organization. But her past storms back, violent and relentless, pulling her into a deadly chase that puts her and her lover’s lives in immediate jeopardy.

The tension is relentless, the pacing razor sharp, and the emotional stakes elevate the story far beyond a typical action thriller. Themes of identity, trust, love, survival, and moral ambiguity make Fatal Decision especially appealing to fans of strong female leads, covert ops thrillers, and morally complex protagonists.

With 36 ratings and strong reviews, the book clearly resonates with thriller fans looking for a blend of action, emotion, and character depth.

Fatal decision is a skilfully constructed action-pack thriller with characters drawn in a brilliant way. It falls into the category of mystery and suspense and revolves around the story of a beautiful, sophisticated, but dreadful femme fatale called Sam. She is a killer who lurks in the shadows while escaping her former employers, the Delphi intelligence, who has controlled her life for a lot of years.
The cover is provocative and has invited me to pick this title out of the Amazon virtual bookshelf. It is made up of 30 chapters with plenty of twists and turns. The author's writing style is simple and there are dialogues mingled in the prose that add realism to actual fiction.
Set between Mexico and the United States, the storyline is out of the ordinary, it has been penned using the sense of pace in a perfect way, even though the sequences of events occur in such a way that would prevent you from putting the book down.

Sam Harker is a skilled Assassin; some would say even the best in her field. She did not choose this life; it was fate that brought her to the attention of the Delphi Intelligence Corporation. After her escape from their control, she has to lay low and go on the run for the reach of the Delphi Intelligence corporation is vast and far reaching. Living life on the lam is not easy and when Sam finally finds someone, she can love and confide in, she wants to settle down, but her past will always catch up to her. Only now, she actually has something to lose.
This was a good book, Sam is an accomplished woman and she does not let her feelings get in the way of what needs to be done to protect herself and her love Jake. A confident and well written female protagonist, Sam was an easy character to like and root for. I like that the author did not make her too emotional nor was she a rock, but that delicate balance was well drawn and written.

I received this book through NetGalley ReadNow program. This story begins by introducing Sam Harker as an assassin. It goes into how she is able to kill two individuals. Later on, you discover what this is really about. She is not an assassin for hire, but one who is taking aim at a mysterious organization. As the story progresses, you will understand what her motive is.

In this instance, her latest actions has squarely placed her on this organizations hit list. They are able to finally discover her after looking for her over the last 2 years. In addition, her boyfriend has unknowingly also become a target. They are ultimately captured and Sam is given an ultimatum that she must follow.

To discover what deed she has been asked to do and how she finishes everything in the end, then you must read this book. I recommend it highly.

An action-packed novel
Fatal Decision: a Sam Harker Thriller is an action-packed story that can keep any reader at the edge of their seats. As the title says, this is a thriller that gives life to a smart strong woman as a main character.
Sam Harker has a painful, criminal past that is difficult to let go. When she falls in love, she prepares herself for the worse: she has decided to do whatever it takes to protect the one she loves. Unfortunately, what she has to do is extremely dangerous, and any step she takes might end up in a catastrophe.
In this story, it is easy to follow this extraordinary character’s way of thinking. The writer of this story let us into her mind, making us fully comprehend her actions, but at the same time making us experience what the character feels.
I recommend this story to teenagers and adults that fancy mysteries and thrillers.

Wow, that was amazing! I love books that highlight a strong female heroine that stands out and can take anything down with her will-power and determination. Fatal Decision: A Sam Harker Thriller by T.L. Wolf is a wonderfully written action and thriller book that surprised me to no end. I loved Sam Harker's character that I was rooting for her to really get through all of the situations coming to her.

I found myself getting nervous at times because I didn't want Sam to get into trouble while she was trying to save Jake. The author succesfully took me on an adrenaline rush with this book. It was well-done and the action scenes were just so crazy! If you like action-packed books with strong female characters, I recommend you to delve into this book!

Fatal Decision A Sam Harker Thriller is T. k. Wolf’s first book in a series. The book is non stop action. Sam was coerced by Delphi a company with many international political connections and involved in maintaining the underbelly of life to become a mercenary. Fleeing from the company put a target on her back. However she uses her skills to financially impact the companies illegal businesses.

I absolutely enjoyed the suspense and intrigue as Sam fights to stop the injustice.

What a remarkable first book from this author. If you like adrenaline-fueled spy stories, David against Goliath, this book is for you. As always, it required a very heavy dose of suspending disbelief (Delphi and the things it does make no sense, sorry), but when you immerse yourself fully you can't help but root for Sam from the first to the very last page.

I received an advance review copy for free, and I am leaving this review voluntarily.

What a fabulous thriller! Action from the begin to the end. Sam is a take no prisoner type that takes aim at her ex-employer. And how scary that such an organization could exist. I was up half the night finishing this book. It was just too good to put down. Excellent!!

I read this book on NetGalley

Fun read with an over the top protagonist. Samantha is an extraordinarily skilled assassin who is out to destroy her prior employers. Some very descriptive violence but overall an exciting story line and a page turner. Good effort by the author.
