Years ago, in the town of Saxon Falls, young Kelsey Willard disappeared and was presumed dead. The tragedy left her family with a fractured life—a mother out to numb the pain, a father losing a battle with his own private demons, and a sister desperate for closure. But now another teenage girl has gone missing. It’s ripping open old wounds for the Willards, dragging them back into a painful past, and leaving them unprepared for where it will take them next.

Bureau of Criminal Investigation agent Mark Foster has stumbled on uncanny parallels in the lives of the two missing girls that could unlock clues to a serial killer’s identity. That means breaking down the walls of the Willards’ long-guarded secrets and getting to a truth that is darker than he bargained for. Now, to rescue one missing girl, he must first solve the riddles that disappeared with another: Kelsey Willard herself. Dead or alive, she is his last hope.
