"An intricate and absorbing plot, leading to a chilling conclusion . . . another powerhouse thriller" from the USA Today bestselling author of Whirlwind (Fresh Fiction). Deep in the woods of upstate New York a woman flees a blazing barn. She is burned beyond recognition, and her dying words point police to a labyrinth of "confinement rooms"--rooms designed to hold human beings captive--where they make other chilling discoveries. In Manhattan, Kate Page, a single mom and reporter with a newswire service, receives a heart-stopping call from a detective on the case. A guardian angel charm found at the scene fits the description of the one belonging to Kate's sister, Vanessa, who washed away after a car crash in a mountain river twenty years ago. Kate has spent much of her life searching for the truth behind her little sister's disappearance. Now, a manhunt for a killer who's kept a collection of victims prisoner for years without detection becomes her final chance to either mourn Vanessa's death--or save her life.
