Desperate for refuge from their abusive family and violence at school, Debra and her sister Madlen seek shelter in the Convent of the Sacred Light. But instead of sanctuary, Debra finds only bloodshed and intrigue. Hidden lusts and deadly secrets haunt the ancient stones of the convent. Worse yet, Debra's own sister is driven by an insane compulsion to destroy her.
Debra has no one to turn to. Her protector, Father Giovanni, is menaced by veiled threats, and her fellow-novice, Nicola - a former Mafia moll - is obsessed with revenge.
Can anything save Debra from her mortal enemy - The Sister?
