Can you change a future that’s already set?

When a deadly explosion rips through her university lab, physics student Olivia Barrett becomes the FBI’s prime suspect. The professors she accused of misconduct are dead. The evidence is stacked against her. And Olivia’s unshakable belief in determinism makes her wonder if fighting back is even possible.

FBI bomb specialist Rachel Quinn isn’t convinced. She’s been hunting a bomber for years — and the trail now circles Olivia. But as bodies pile up and time itself begins to fracture, the past and future blur into patterns neither woman can ignore.

Now one question remains: how far will someone go to rewrite the past?

Fixed Point is a dark, time-twisting psychological thriller for fans of Lauren Beukes’ The Shining Girls and Blake Crouch’s Dark Matter. If you love thrillers where obsession, inevitability, and fractured timelines collide, this one will leave you breathless.

IndieReader

"A Wild, Smart, Unapologetic Ride! I devoured this book in about two sittings. This is a fast-paced thriller that doesn’t let up, full of twists, turns, and, yes, time travel (which I always love). Lately, I’m just really tired of reading the same recycled plots or just another rehash from a different point of view. And so many books feel like there’s no real peril because you know nothing bad is going to happen. This book is different. It’s just grounded and gritty. And what really surprised me is that the ending doesn’t try to be cute. It’s not neatly wrapped up with a pretty little bow. It’s practical, and a bit unsettling in the best way. Also, side note, I have a PhD in chemistry and I’ve dealt with exactly the kind of toxic mentor that shows up in this story, so that part hit way too close to home. Highly recommend."

Alice - reader reviewer

"Mindblowing read!!!! This was a brilliant story that kept me guessing and invested throughout the story. I was tired, but I needed more and kept reading until I finished this. I sat in silence processing it and letting it soak in. This is the type of book I love. It felt so full of possibilities and promises that resonated with me. A must read."

Beverly - reader reviewer

"Reading Fixed Point took me on a journey through time. The fast paced adventure held my attention through out the entire journey. I devoured this book trying to read faster and faster for the conclusion. There were character twists and developments that I was not prepared to unfold. Fixed point follows two main characters. One trying to solve a bombing and the pleading her innocence. The doubtful FBI agent learns there is more to our world than what meets the eye. Time travel is very real and possible. Her suspect holds the key to her entire investigation. No one can change their fate. You cannot change anything. I thoroughly enjoyed this adventure."

Kristan - reader reviewer

"Twisted Time Thriller. Anyone who has watched and remembers, or even the commercials, will know the reference to the name 'Mulder'. That was a dead give away that this would not be a simple straight forward story, and it was not! It kept me going at every change to know that it was not over, yet. Right up to the end, and is it over...? I loved the passion for the work, safety, knowledge, and wanting to know what they do not remember, and why it just does not 'feel right'. Thank you, Lynn M. Kristopher, for a great story!"

Tina - reader reviewer

"A convoluted mystery full of twists and turns. An enjoyable read."

Maria - reader reviewer

"A thrilling read that twists and lays down false trails. A bomber from the past that has pulled Olivia into their grasp. Blamed for the explosion by others, but did she actually do the deed. Only a few believe her innocent and she isn't sure herself. A thriller that will hold your interest. And maybe a few shivers from memories of trying to complete your own PHD programs."

Terri - Reader Reviewer

Rachel was supposed to be taking a break in Florida after the strange events of Fixed Point. But when her niece calls for help at a veterinary conference, Rachel is pulled into an investigation involving a series of deadly poisonings.

When a powerful hurricane strikes—leaving the attendees trapped inside—the investigation quickly escalates into cartel violence, corporate conspiracy, and something far more unsettling.

As the storm worsens, survival may depend on understanding a threat that defies the laws of the world she knows. And Rachel must navigate shifting truths where nothing—and no one—is quite what it seems.

Not Who She Was is a dark, psychological thriller with a speculative twist and high-concept elements for fans of Lauren Beukes and Blake Crouch. If you love thrillers that blend conspiracy, isolation, and unraveling realities, this one will keep you turning pages late into the night.
