The Call of the Wild is a novel by American writer Jack London. The plot concerns a previously domesticated dog named Buck, whose primordial instincts return after a series of events leads to his serving as a sled dog in the Yukon during the 19th-century Klondike Gold Rush, in which sled dogs fetched generous prices. Buck learns from his experiences and becomes a pack-dominating feral beast. He learns lessons and relies on resurgent behaviors inherited from his wild predecessors, helping him to survive adversity as a ferocious animal.
Published in 1903, The Call of the Wild is London's most-read book, and it is generally considered his best, the masterpiece of his so-called "early period". Because the protagonist is a dog, it is sometimes classified as a juvenile novel, but it is dark in tone and contains numerous scenes of cruelty and violence. The Yeehat, a group of Alaska Natives portrayed in Call of the Wild, were a figment of London's imagination.
