In the bitter cold of a Montreal winter, Tempe Brennan is digging for a corpse buried more than a century ago. While Tempe thrives on such enigmas from the past, it's a chain od contemporary deaths and disappearances that have seized her attention - and she alone is ideally placed to make a shattering connection among the seemingly unrelated events. At the crime scene, at the morgue, and in the lab, Tempe probes mystery that sweeps from a deadly Quebec fire to startling discoveries in the Carolinas, and culminates in Montreal with a terrifying showdown - a nerve-shattering test of both her forensic expertise and her skills for survival.
