When 15-year-old Billy Wilkinson goes missing from his home in Bristol, England, in the middle of the night, his mother, Claire, blames herself. She's not the only one. There isn't a single member of Billy's family that doesn't feel guilty. Six months later, after an appeal for information goes horribly wrong, the truth finally begins to surface. Claire is sure of two things--that Billy is still alive and that her friends and family had nothing to do with his disappearance. A mother's instinct is never wrong. Or is it...? A harrowing psychological thriller from the author of The Lie (2016).
