The Call of the Wild is regarded as Jack London's masterpiece. Based on London's experiences as a gold prospector in the Canadian wilderness and his ideas about nature and the struggle for existence, The Call of the Wild is a tale about unbreakable spirit and the fight for survival in the frozen Alaskan Klondike. The story takes place in the extreme conditions of the Yukon during the 19th-century Klondike Gold Rush where strong sled dogs were in high demand. After Buck, a domesticated dog, is snatched from a pastoral ranch in California, he is sold into a brutal life as a sled dog. The work details Buck's struggle to adjust and survive the cruel treatment he receives from humans, other dogs, and nature. He eventually sheds the veneer of civilization altogether and instead relies on primordial instincts and the lessons he has learned to become a respected and feared leader in the wild. White Fang is the story of a wild dog's journey toward becoming civilized in the Canadian territory of Yukon during the Klondike gold rush at the end of the nineteenth century. White Fang is a companion novel (and a thematic mirror) to Jack London's best-known work, The Call of the Wild, which concerns a kidnapped civilized dog turning into a wild wolf. The book is characteristic of London's precise prose style and his innovative use of voice and perspective. Much of the novel is written from the viewpoint of the animals, allowing London to explore how animals view their world and how they view humans. Jack London (1876–1916) was an American novelist, journalist, and social activist. A pioneer in the world of commercial magazine fiction, he was one of the first writers to become a worldwide celebrity and earn a large fortune from writing. He was also an innovator in the genre that would later become known as science fiction.
