It only takes one fleeting moment for Liz Camden to change the lives of everyone she loves.

The community along Oregon's Deschutes River is one of successful professionals and perfect families. For years, up-and-comers Liz and Owen have admired their good friends and neighbors, Carole and David. They appear to have it all--security, happiness, and a beautiful young son, Charlie.

Then Charlie vanishes without a trace, and all that seemed safe is shattered by a tragedy that is incomprehensible--except to Liz. She can't undo the terrible mistake she made. Or her unforgiveable decision to conceal it.

As two marriages crack and buckle in grief and fear, Liz retreats into her own dark place of guilt, escalating paranoia, and betrayals even she can't imagine. Because there's another good neighbor who has his own secrets, his own pain, and his own reasons for watching Liz's every move. . . . Someone who knows that the mystery of the missing boy on the Deschutes River is far from over.
