Sonia, forty-three, is a strikingly attractive wife and mother with a lovely house overlooking the Thames in London. Her life is a picture of perfection and normalcy. But when fifteen-year-old Jez, the gorgeous nephew of a neighbor and friend, shows up on her doorstep one evening, she's prepared to sacrifice it all to keep him. Fiercely drawn to Jez by a compulsion that she scarcely understands, Sonia finds herself holding him hostage in her home, awakening a torrent of memories.
