Welcome to Walt Longmire's worst nightmare. Winter is creeping closer, but for Sheriff Longmire this one is looking to be harsh in a way to which he is wholly unaccusstomed. He has found himself in the remotest parts of the northern Mexican desert, a lawless place where no horse or car can travel, where no one speaks his language or trusts an outsider, far from his friends and his home turf back in Wyoming. But desperate times call for desperate measures. Walt and Tomas Bidarte, the head of one of the most vicious drug cartels in Mexico, have been circling each other in a deadly cat-and-mouse game for more than a year. Now, Bidarte has kidnapped Walt's beloved daughter, Cady. The American government is of limited help and the Mexican one even less so. Armed with his trust Colt .45, a father's intuition, and the keen instinct on which he's staked his reputation and life more than once, Walt must head into the 110-degree heat of the desert, one man against an army. Depth of Winter is the fourteenth novel in Craig Johnson's beloved New York Times bestselling Longmire series.
