"Out of the frozen depths of a forest in Omberg, Sweden, a woman stumbles onto the road. Her arms are covered with scratches, her feet are bare, and she has no memory of what has happened. Local police identify her as psychological profiler Hanne Lagerlind-Schoen who, together with her partner, had been helping them investigate a cold case of a young woman's murder. Hanne begins to recover, but cannot recall anything about where her partner is, or what their investigation had uncovered before her disappearance. Police have only one lead: a young woman in a sequin dress who was spotted walking down the road the night Hanne was found. The young woman doesn't come forward, because she doesn't exist: Jake Olsson, a local teenager, had been out walking in his mother's dress and sister's makeup, his secret shame and thrill. Terrified of discovery, Jake hid when the car appeared and watched Hanne get into it, realizing too late that she left a diary behind. As Jake reads Hanne's notebook, he realizes it contains the key to a major breakthrough in the case. But turning in the diary would mean admitting the truth about who he is. When another murder victim is found in the woods, Jake realizes Hanne herself is in danger, and his only choice is to find and warn her so together they can stop him before he kills again"--
