Madeline Dare has finally escaped rust-belt Syracuse, New York, for the lush Berkshire Mountains in Massachusetts. After her husband's job offer falls through, Maddie signs on as a teacher at the Santangelo Academy, a boarding school for disturbed teenagers. Behind the academy's ornate gates, she discovers a disturbing realm where students and teachers alike must submit to the founder's bizarre therapeutic regimen. From day one, Maddie feels uneasy about smooth-talking Dr. Santangelo but when she questions his methods, she's appalled to find that her fellow teachers would rather turn on each other than stand up for themselves, much less protect the students in their care. A chilling event confirms Maddie's worst suspicions, then hints at an even darker secret history, one that twines through the academy's very heart. Cut off from the outside world, Maddie must join forces with a small band of the school's most violently rebellious students-kids whose troubled grip on reality may well prove to be her only chance of salvation.
