Generally considered to be "the earliest of the modern Dystopian," it chronicles the rise of an oligarchic tyranny in the United States. It is arguably the novel in which Jack London's socialist views are most explicitly on display. A forerunner of soft science fiction novels and stories of the 1960s and 1970s, the book stresses future changes in society and politics while paying much less attention to technological changes.
As Buck, a mixed breed dog, is taken away from his home, instead of facing a feast for breakfast and the comforts of home, he faces the hardships of being a sled dog. Soon he lands in the wrong hands, being forced to keep going when it is too rough for him and the other dogs in his pack. He also fights the urges to run free with his ancestors, the wolves who live around where he is pulling the sled.
