From the outside, criminal psychiatrist Dr. Madeline Pine's life appears picture-perfect--she has a beautiful family, a successful mental health practice and a growing reputation as an expert in female violence. But when she's called to help investigate a mysterious death at a boarding school for troubled girls, Madeline hesitates. She's been through tragic cases before, and the one she was entangled in last year nearly destroyed her... Yet she can't turn away when she hears about Charley Ridley. After the girl was found shoeless and in pajamas at the bottom of an icy ravine on campus, the police ruled it a tragic accident. But the private investigator hired by her mother has his doubts. If it were Madeline's daughter who died, she'd want to know why. Arriving at the secluded campus in upstate New York, Madeline's met by an unhelpful skeleton staff and the four other students still on campus during winter break. Each seems to hold a piece of the puzzle. And everyone has secrets--Madeline included. But who would kill to protect them?
