The Call of the Wild is a novel by Jack London published in 1903. The novel's central character is Buck, a domesticated dog living at a ranch in the Santa Clara Valley of California as the story opens. Stolen from his home and sold into service as sled dog in Alaska, he reverts to a wild state. Buck is forced to fight in order to dominate other dogs in a harsh climate. Eventually he sheds the veneer of civilization, relying on primordial instincts and learned experience to emerge as a leader in the wild.London lived for most of a year in the Yukon collecting material for the book. The novel's great popularity and success made a reputation for London. Much of its appeal derives from the simplicity of this tale of survival. As early as 1908 the story was adapted to film and it has since seen several more cinematic adaptations. LONDON JACK Jack London nace en San Francisco, en 1876.
