It’s sweltering in Charlotte, North Carolina, and Temperance Brennan, still recovering from neurosurgery following an aneurysm, is battling nightmares, migraines, and what she thinks might be hallucinations when she receives a series of mysterious text messages, each containing a new picture of a corpse that is missing its face and hands. Immediately, she’s anxious to know who the dead man is, and why the images were sent to her. An identified corpse soon turns up, only partly answering her questions. To win answers to the others, including the man’s identity, she must go rogue, working mostly outside the system. That’s because Tempe’s new boss holds a fierce grudge against her and is determined to keep her out of the case. Tempe bulls forward anyway, even as she begins questioning her instincts. But the clues she discovers are disturbing and confusing. Was the faceless man a spy? A trafficker? A target for assassination by the government? And why was he carrying the name of a child missing for almost a decade?
