A terrified young woman leaves a phone message for her grandfather. He promised he'd protect her, but now she's disappeared. A little girl, only three years old, is found half-dead on a deserted mountainside. No one has reported her missing. Someone left her there to die. The two cases seem unconnected, but Dr Clare Hart can see a terrifying pattern emerging. Can she find Rosa? Or is it already too late?
