On the Oregon coast stands Siren Song, home to a group of women known as The Colony. Their aunt hoped the lodge would be a sanctuary, a place where she could protect them and their special gifts. But nowhere is safe from the man who has marked them for death. The note pinned to the body found on the beach has no name, just Ravinia Rutledge's phone number and the words Next of Kin. Ravinia insists she doesn't recognize the man on the mortuary slab, but she suspects Detective Nev Rhodes doesn't believe her. He can tell that she's one of them-the Siren Song women. Five years after moving away from The Colony, Ravinia has created a life as a PI specialising in locating missing loved ones. "Good Time Charlie" is the name given to a monster from her past, a man she and her sisters hoped was gone forever. But the dead man on the beach is a sign that Charlie has been waiting, preparing to rid the world of the Siren Song women-and anyone who gets in his way.
