The seventh book in the New York Times bestselling Longmire series, featuring Sheriff Walt Longmire.

Raynaud Shade, an adopted Crow Indian and one of the country's most dangerous sociopaths, has just confessed to murdering a boy twenty years ago and burying him deep within the Bighorn Mountains. Absaroka County Sherriff Walt Longmire must escort Shade through a snowstorm to the site, but the mission turns personal when Walt learns whom the dead boy's family is.

Guided only by Indian mysticism and a battered paperback of Dante's Inferno, Walt braves the icy hell of the Cloud Peak Wilderness Area, cheating death to ensure that justice - both civil and spiritual - is served.
