A newborn baby is found wedged in a vanity cabinet in a rundown apartment near Montreal. Dr Temperance Brennan, forensic anthropologist to the province of Quebec, is brought in to investigate. While there, she discovers the mummified remains of two more babies within the same room.

Shocked and distressed, Tempe must use all her skills and inner strength to focus on the facts. But when the autopsies reveal that the children died of unnatural causes, the hunt for the mother - a young woman with a seedy past and at least three aliases - is on. The trail leads Tempe to Yellowknife, a cold, desolate diamond-mining town on the edge of the Arctic Circle, where her quest for the truth only throws up more questions, more secrets, and more dead bodies.

Taking risks and working alone, Tempe refuses to give up until she has discovered why the babies died. But in such a hostile environment, can she avoid being the next victim?
