Ever since her father was stabbed to death, Jules Farentino has been plagued by nightmares. Her teenaged sister Shay has reacted with a rap sheet for drug use, theft and vandalism. Still, when her mother decides to send Shay to an elite boarding school in Oregon, Jules is worried. The Academy has a reputation for turning wayward kids around - but one of its students went missing six months ago and her body has never been found. On impulse, Jules applies for a teaching job at the Academy. Just before she arrives, a student is found hanged, and a hysterical Shay believes it was murder. Then another girl goes missing, and yet another is found dead. Behind the Academy's idyllic veneer lurks an evil force on a brutal and terrifying mission. And Jules is the next target of a bloodthirsty killer without limits, without remorse, without mercy.
