Every instinct tells him to run. Every memory tells him he can’t.

Special Agent Daniel Stansfield is ready for a change. Burnt out and defeated by the job, it’s his last day with the FBI. But before he can turn in his badge, he’s summoned back to Denver, the city he ran from four years ago, with a chilling message: it’s happening again.

Seemingly innocent people are waking up on the side of the highway, with no memory of how they got there, wearing the skin of victims they’ve allegedly never met. And they each share one haunting detail: a strand of a stranger’s hair is tied around their tongue.

Now Daniel is pulled back into the gruesome cycle, and every clue leads him deeper into the shadows of his own past. He will have to confront the ghosts of his traumatic childhood and face what’s been hunting him all along― before he and the people he loves become the next victims.
