Perfect for you if...

You love crime thrillers with a personal vendetta at the heart, where the detective's trauma drives the investigation forward.
You're drawn to protagonists with unusual skills (hypnosis, photographic memory) that give them an edge but also complicate their lives.
You appreciate Southern Gothic settings and want a story rooted in a specific place, not generic FBI procedural.

Maybe not for you if...

You need standalone thrillers with neat endings; this is book one of a series and builds ongoing mythology.
You prefer procedurals that focus on investigation tactics over character backstory and emotional stakes.
You want to avoid stories centred on violence against women, even when told from a survivor's perspective.

About this book

Sophie Quinn was once a hypnotist with her own TV show. Now she works as a full-time FBI consultant. Six years ago, she became the River Killer's intended tenth victim but managed to escape her bindings—unlike the others he killed, including her sister. With two PhDs and a photographic memory, Quinn is now a rising star at the FBI. She remembers the killer's tattoo and his voice. Ten years after her escape, he is active again. Quinn returns to her hometown in Louisiana along the Mississippi River to find the man responsible for her sister's death and confront him. She hasn't been home in six years, and broken relationships and shattered dreams await her among the bayous, rivers, waterways, and swamps. As she pursues the killer, Quinn faces the question of whether she will find her way home again—or become his next victim.
