In this quintessential adventure story, Jack London takes readers on an arduous journey through the forbidding Alaskan landscape during the gold rush of the 1890s. Buck, a rangy mixed breed used to a comfortable, sun-filled life as a family dog, is stolen by a greedy opportunist and sold to dog traffickers. In no time, Buck finds himself on a team of sled dogs run ragged in the harsh winter of the Klondike. In a climate where every day is a savage struggle for survival, the last traces of Buck's soft, pampered existence are erased as his dormant primordial urges -- deeply embedded for generations -- are brutally awakened.
