A gripping Temperance Brennan novel from world-class forensic anthropologist Kathy Reichs, the international no. 1 bestselling crime thriller writer and the inspiration behind the hit TV series Bones. On a bitterly cold March night in Montreal, forensic anthropologist Dr Temperance Brennan is exhuming the remains of a nun in the grounds of an old church. Hours later, Tempe is called to the scene of a horrifying arson. A young family has perished, but there is no explanation, no motive, and no witnesses. From the charred remains of the inferno, to a trail of sinister cult activity, Tempe faces a nerve-shattering case which will test her forensic expertise - and her instinct for survival.
