In this electrifying tale of suspense from an international crime-writing sensation, a grisly death exposes the dark heart of a Scandinavian seaside village. Erica Falck returns to her tiny, remote hometown of Fjällbacka, Sweden, after her parents’ deaths only to encounter another tragedy: the suicide of her childhood best friend, Alex. It’s Erica herself who finds Alex’s body—suspended in a bathtub of frozen water, her wrists slashed. Erica is bewildered: Why would a beautiful woman who had it all take her own life? Teaming up with police detective Patrik Hedström, Erica begins to uncover shocking events from Alex’s childhood. As one horrifying fact after another comes to light, Erica and Patrik’s curiosity gives way to obsession—and their flirtation grows into uncontrollable attraction. But it’s not long before one thing becomes very clear: a deadly secret is at stake, and there’s someone out there who will do anything—even commit murder—to protect it.
