Number One bestselling author Harlan Coben has become an unstoppable force in crime fiction. His most recent novel, THE WOODS, was a SUNDAY TIMES top 2 bestseller and grew his audience by an impressive 20%. His latest page-turner, which is about just how far parents will go to protect their kids, is destined for the top of the charts. Tia and Mike Baye never imagined they'd become the type of overprotective parents who spy on their kids. But their sixteen-year-old son Adam has been unusually distant lately, and after the suicide of his classmate Spencer Hill-the latest in a string of issues at school-they can't help but worry. They install a sophisticated spy program on Adam's computer, and within days they are jolted by a message from an unknown correspondent addressed to their son: "Just stay quiet and all safe." Meanwhile, browsing through an online memorial for Spencer put together by his classmates, Betsy Hill is struck by a photo that appears to have been taken on the night of her son's deathand he wasn't alone. She thinks it is Adam Baye standing just outside the camera's range, but when Adam goes missing, it soon becomes clear that something deep and sinister has infected their community. For Tia and Mike Baye, the question they must answer is this: When it comes to your kids, is it possible to know too much?
