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 were bought at generous prices. 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, suitable for children, but it is dark in tone and contains numerous scenes of cruelty and violence. The Yeehat, a group of Alaska Natives portrayed in The Call of the Wild, are a figment of London's imagination.
