Oregon's Deschutes River. For years Liz and Owen have admired their neighbors, Carole and David, who seem to have it all: security, happiness, and a beautiful son, Charlie. Then Charlie vanishes without a trace. In a heartrending accident, Liz has changed the lives of everyone she loves-- and is concealing it. As two marriages buckle in grief and fear, Liz retreats into guilt and paranoia... and another neighbor has his own secrets, his own pain, and his own reasons for watching Liz's every move.
