Stay close - Harlan Coben

Megan once walked on the wild side. Now she's got two kids, a perfect husband, a picket fence, and a growing sense of dissatisfaction. Ray used to be a talented documentary photographer, but at age forty he finds himself in a dead-end job posing as a paparazzo pandering to celebrity-obsessed rich kids. Broome is a detective who can't let go of a cold case - a local husband and father disappeared seventeen years ago, and Broome spends the anniversary every year visiting a house frozen in time, the missing man's family still waiting, his slippers left by the recliner as if he might show up any moment to step into them.

Three people living lives they never wanted, hiding secrets that even those closest to them would never suspect. As the terrible consequences of long-ago events crash together in the present and threaten to ruin lives they will discover the hard truth that the line between one kind of life and another can be as whisper-thin as a heartbeat...
