A diabolical psychological thriller, perfect for fans of Gone Girl and Defending Jacob. Dr. Shelby Cooper is a brilliant research scientist with a past steeped in secrets and lies--lies about her true identity, her family, and the one regrettable mistake she made as a teenager. But Shelby is a survivor and now lives the life she only dreamed of with her powerful executive husband, and two adorable kids in a picturesque New England town. When her ex-lover is discovered shot to death in the trunk of her car, overwhelming evidence points to Shelby as the killer, and to the police, it's an open-and-shut case. For the Cooper family, it's the beginning of a terrifying nightmare where nothing is as it seems. Who is Shelby Cooper? And why does the psychopath stalking her teenage daughter Abbie insist she has done bad things? To unmask a killer and rescue his wife from a possible murder conviction, Jason Cooper must unravel the mystery of Shelby's past. As the clock ticks, a series of shocking revelations threaten to destroy the Coopers for good. But nothing can prepare them for the mother of all deception--a truth so horrifying, it may leave them shattered forever.
