Parents will find this compulsive page-turner from Edgar-winner Coben (The Woods
) particularly unnerving. A sadistic killer is at play in suburban Glen Rock, N.J., outside New York City, but somehow he's less frightening than the more mundane problems that send ordinary lives into chaos. How do you weigh a child's privacy against a parent's right to know? How do you differentiate normal teenage rebelliousness from out-of-control behavior? When and how do you intervene if suicidal signs appear? Other issues include single parenting; career versus family; marital honesty; and how much information you should share with a child at what age. Coben plucks each of these strings like a virtuoso as Mike and Tia Baye try to deal with the increasing withdrawal of their 16-year-old son, Adam, after a friend's suicide. A pair of brutal, seemingly senseless killings, punctuate the unfolding domestic troubles that ratchet up the tension and engulf the Baye family, their friends and neighbors in a web of increasing tragedy. The “this could be me” factor lends poignancy to the thrills and chills. (Apr.)
