In this nerve-shattering novel from the New York Times bestselling author of Alone in the Dark, special agents Griffin Davenport and Kate Coppola are on the trail of a depraved criminal.

When Special Agent Griffin "Decker" Davenport opens his eyes after several days in a coma, there is unfinished business still on his mind. Decker is on the cusp of discovering the mastermind behind a human trafficking case, and he and his partner, Special Agent Kate Copolla, are about to get a surprising new lead from a very unlikely source.

Eighteen-year-old Mallory Martin and her little sister Macy were the victims of an illegal adoption—sold by their addict mother for drugs. But their "benefactor" is not who everyone thinks he is. Mallory has never told his secrets before—the danger to her and her sister has always been too great. But everyone has a limit to what they can endure.
