Sixteen-year-old Jenny Lind is kidnapped in broad daylight on her way home from school and thrown into the back of a truck. Shes taken to a dilapidated house, where she and other girls face horrors far beyond their worst nightmares. Though theyre desperate to escape, their captor foils everyone of their attempts. Five years later, Jennys body is found hanging in a playground, strung up with a winch on a rainy night. As the police are scrambling to find a lead in the scant evidence, Detective Joona Linna recognizes an eerie connection between Jennys murder and a death declared a suicide years before. And when another teenage girl goes missing, it becomes clear to Joona that theyre dealing with a serial killer-and his murderous rampage may have just begun.
