Claudia's life imploded ten years ago when she was convicted of the murder of her child. Now she has done the unthinkable and confessed to manslaughter in order to be granted parole - her only hope of finding out what really happened to Tilly.

Sara is married to Joe, Claudia's ex-husband, and they have a young child together. She finally has everything she ever wanted, but Claudia's release threatens the perfect life she has created.

Anna was the babysitter who let Claudia and Joe down on day their daughter disappeared. Married with a child of her own, Claudia's reappearance in her quiet cul-de-sac is an unwelcome surprise.

These three women are tied together in more ways than they realize. But only one of them is capable of killing.
