In Texas a serial killer is executed, taking to his grave the identity of his only child. In Boston a nine-year-old girl is abandoned in a hospital, then adopted by a wealthy young couple. Twenty years later, Melanie Stokes still considers herself lucky. Until... Melanie had lost all memory of her life before the adoption, and now someone wants to give it back. Even if it includes the darkest nightmare the Stokes family ever faced: the murder of their first daughter in Texas. As Melanie pursues every lead, chases every shadow in the search for her real identity, two seemingly unrelated events from twenty years ago will come together in a dangerous explosion of truth. And with her very life at stake, Melanie will fear that the family she loves the most may be the people she should trust the least.
