"Suspense doesn't get much smarter than this." (Lee Child). "Crime-writing at its unputdownable, nerve-tingling best." (Harlan Coben Murder). That's what they all have in common. Detective Jane Rizzoli and Forensic Pathologist Maura Isles find themselves locked inside a high-security boarding school along with the students. They are told it's for their own safety. The school has been set up to provide a place of sanctuary for children who have lost their families in violent circumstances. But now there has been a murder within the grounds. Does the threat come from outside...or from within?
