Bestselling author Tess Gerritsen is also a physician, and she brings to her novels her first-hand knowledge of emergency and autopsy rooms. Her thrillers starring homicide detective Jane Rizzoli and medical examiner Maura Isles inspired the hit TV series Rizzoli & Isles . But Tess's interests span far more than medicine and crime. As an anthropology student at Stanford University, she catalogued centuries-old human remains, and she continues to travel the world, driven by her fascination with ancient cultures and bizarre natural phenomena.

If it's gripping, it's Gerritsen. A terrifying Rizzoli and Isles bestseller.

Not even the icy temperatures of a New England winter can match the bone-chilling scene of carnage discovered in the early morning hours at the chapel of Our Lady of Divine Light. Within the sanctuary walls of the cloistered convent, now stained with blood, lie two nuns - one dead, one critically injured: victims of an unspeakably savage attack. The brutal crime appears to be without motive and the elderly nuns in residence offer little help in the police investigation. But medical examiner Maura Isles' autopsy of the dead woman, twenty-year-old Sister Camille, yields a shocking surprise. The disturbing case takes a stunning new turn when another woman is found murdered in an abandoned building, her features obliterated. Together, Isles and homicide detective Jane Rizzoll uncover an ancient horror that connects these terrible slaughters. As long-buried secrets come to light, Maura Isles finds herself drawn inexorably towards the heart of an investigation that seems to be spiralling closer and closer to home, and the slow but shattering realisation of the killer's identity.
