When Linda Bluenight's teenage son, Matty, stumbles across a corpse while hiking in Ventana Canyon, her past experience in forensic anthropology catches up with her. The short-handed Tucson PD asks for her help with the autopsy, and her findings lead her to believe the Tohono O'odham boy arrested for the crime is not guilty. As she investigates a lengthy list of suspects, Linda and her son both become targets for an unknown adversary bent on scaring her off the scent and back to the day job she loves - teaching children at the San Xavier del Bac Mission school. But Linda and Matty are not so easily put off, and when Linda begins to get close to the truth, she finds herself in more danger than she anticipated.
