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 are jolted by a message from an unknown correspondent addressed to their son: ?Just stay quiet and all is 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 death . . . and 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?
