From the Amazon Charts and #1 New York Times bestselling author comes a psychological thriller exploring the things we dare to do when no one is looking . . . The community along Oregon’s Deschutes River is one of successful careers 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. It took one fleeting moment for her to change the lives of everyone she loves—a heartrending accident that can’t be undone. Neither can the second-worst mistake of her life: concealing 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. And only he knows that the mystery of the missing boy on the Deschutes River is far from over.
