A nine-year old girl dies on her way to ballet class, caught in outlaw biker crossfire. Violence is spilling on to the streets of Montreal and Dr Temperance Brennan, forensic anthropologist for the state, has to pick up the pieces.
She knows she shouldn't let emotion get in the way of her role as scientist, but when nine-year-old Emily's body is wheeled into the morgue she cannot help but react. Tempe's nephew, Kit, is mesmerised by motorcycles. Does he understand the dangers posed by the outlaw gangs?
An exhumation uncovers the bones of another innocent, hidden in a clandestine grave close to a biker headquarters. With her boss in the hospital and her sparring partner Andrew Ryan disturbingly unavailable, Tempe begins a perilous investigation into a lawless underworld of organised crime.
