In a world of lies, the truth is her deadliest weapon.

Sierra Coleman awakens from a horrific crash, her mind a blank slate. But as she claws her way back to reality, she discovers her amnesia is just the tip of a sinister iceberg. Every "truth" she uncovers is another lie, every ally a potential enemy.

With a daughter she can't remember and a life she doesn't recognize, Sierra is thrust into a high-stakes game of cat and mouse. As bodies pile up and shocking betrayals come to light, she realizes the key to her survival lies buried in her forgotten past.

Barker's razor-sharp prose slices through the pages, each revelation more stunning than the last. This relentless, twist-filled rollercoaster will have you questioning everything until its explosive finale.
