'The Call of the Wild' is one of London's most popular novels. The story follows a dog named Buck, a 140lb Saint Bernard and Scotch Shepard mix. Buck is abducted from a comfortable life as a pet and tossed into the chaos of the Klondike Gold Rush and the brutal realities of frontier life. A companion novel to 'The Call of the Wild,' 'White Fang' is the story of a wild dog's journey toward becoming civilized.
