When fifteen-year-old Billy Wilkinson goes missing in the middle of the night, his mother, Claire, is distraught, blaming herself. She's not the only one. There isn't a single member of Billy's family who doesn't feel guilty.
But the Wilkinsons are so used to keeping secrets from one another that it isn't until six months later, when an appeal for information goes horribly wrong, that the terrifying truth begins to surface.
Claire is sure of two things: Billy is still alive and her family had nothing to do with his disappearance.
A mother's instinct is never wrong. Or is it?
