Fans of New York Times bestsellers Gone Girl by Gillian Flynn, The Girl on the Train by Paula Hawkins, and The Silent Wife by A.S.A. Harrison will love Penny Hancock’s chilling debut thriller about a woman on the edge. When her neighbor’s fifteen-year-old nephew goes missing, Sonia is the last person that anyone would suspect. At forty-three, she is a strikingly attractive wife and mother. And like the River House, her lovely home overlooking the Thames, Sonia’s life is a picture of perfection and normalcy – until she meets Jez. From the moment he shows up on Sonia’s doorstep, the gorgeous teenage boy awakens a torrent of memories that threaten to reveal a terrifying truth. Drawn to Jez by a compulsion that she scarcely understands, Sonia takes him captive – prepared to sacrifice everything to keep him.
