Imposter is a gripping, adrenaline‑charged thriller that hooked me from the very first page and refused to let go. Fletcher Felix delivers a mind‑bending story packed with tension, twists, and the kind of psychological suspense that keeps you reading long past bedtime.
The novel opens with a jolt: Katherine wakes up beside her husband—perfectly ordinary, except for one impossible detail. She knows she killed him the night before. From that moment on, the book becomes a wild, disorienting ride as Katherine confronts the terrifying question: If this isn’t her husband, then who is he?
Felix masterfully layers mystery upon mystery, pulling the reader deeper into Katherine’s frantic search for answers. Just when you think you’ve cracked the puzzle, the story veers in a new direction, proving you wrong again and again. The pacing is relentless, the atmosphere electric, and the stakes only climb higher as the truth inches closer.
Katherine is a compelling, complex protagonist—vulnerable yet determined, shaken yet sharp. Following her through this maze of deception is half the thrill.
If you love psychological thrillers that keep you guessing until the final reveal, Imposter is an absolute must‑read. Buckle in, because this book doesn’t just surprise you—it blindsides you in the best possible way.

That ending though. So I will say I would NEVER have correctly predicted that outcome in a million years. The only thing that burns me is Marnie still being alive after all that. What a scummy woman with an equally scummy man. I was glad Billy was dead from the jump because the more I learned who he was as a person the more I cheered for Katherine. The only real issue I had was the damn near CONSTANT repetition of "because I killed my husband" like girl...we KNOW. It doesn't have to be said in every single chapter. I did appreciate that the chapters were short making this a fast paced read that actually had really good twists throughout and kept me reading. I felt anxiety when I should, and was actually fairly impressed with this book. 4 stars because of the repetition. It actually became predictable when she would remind me and occasionally took me out of the story and made me roll my eyes. It was very good otherwise!

Great story with some unexpected plot twists

Katherine is a southern wife who does all the house stuffs for her ungrateful husband. She puts some hemlock in his coke and he dies. She buries him in the woods behind their house. But then wakes up the next morning and he’s in bed with her. She starts questioning whether or not she actually killed and buried her husband, and a couple of the imposter’s behaviors don’t line up exactly. She figures out who the imposter is but not why he has injected himself into her life. And she doesn’t ask him directly. She play detective and finds out some stuff. The ending is great and completely unexpected.

I like that the book and twists stayed realistic, and still unexpected! The main character, Katherine, spends the book struggling with processing her own generational trauma and the way that she struggles with how she is seen as a woman felt really relatable. The mystery of the Imposter keeps the story fast paced and I honestly never saw those twists coming! I couldn’t put it down, and really enjoyed it.

What. A. Ride. 🤯 I don't know what I can possibly say about this book that would not give away anything, so I'll stick to how it made me feel instead. I am usually good at predicting the endings. Not this one! Every time I thought I *might* know what was "real," I was quickly proven wrong. I have emotional and mental whiplash, in the best way! Definitely one of the best thrillers I've read in a while!

Imagine going to sleep knowing for a fact that your husband isn’t going to be laying beside you when you wake. Or at least he shouldn’t be. Only……he is and you can’t say a word. Take a wild journey with Katherine and her husband as we learn all about the Imposter. This was my first read from Fletcher Felix and it took me on a roller coaster! I couldn’t put it down! If you’re a fan of shorter chapters like me, you should consider giving Imposter a try!

Katherine kills her jerk of a husband and spends most of the night burying him in the woods behind their house. When Katherine wakes up in the morning, an imposter is lying in bed beside her and very much alive. Who is this imposter and why is he here? This was a twisty story told from the viewpoints of Katherine and the imposter. I was entertained, but I didn't care for the very end.

[Stacy Bishop · Rating 4 out of 5]

Impostor is a stocking, domestic thriller with short chapters and unexpected twists. This book will keep you guessing to the very end. Everytime I thought I had it figured out a new twist was throughout. If you want a book that keeps you guess Imposter is the book for you!

This was my first book by this author and I really enjoyed it! Katherine had quite the story, and it did not end how I thought it would.

I found the story of this book so outrageous and unbelievable. Didn't enjoy it at all.
