MURDER. FIRE. REVENGE. That's all seventeen-year-old Alice Monroe thinks about. Locked in a mental ward at Savage Isle, Alice is haunted by memories of the fire that killed her boyfriend, Jason. A blaze her deranged and jealous sister, Cellie, set. When whispers from other mental patients convince Alice that Cellie has also been committed to Savage Isle, Alice vows to avenge the life of the boy she loved. Aided by Chase, a mysterious, charismatic new patient, Alice stealthily combs Savage Isle for her sister by night, while by day she plays "the good girl," attending group therapy sessions and writing the story of her troubled past in foster care - a past she barely understands - in a journal. But nothing at Savage Isle is what it seems. And no one will leave the same.
