The Call of the Wild, London’s elemental masterpiece about a dog learning to survive in the wilderness, sees pampered pet Buck snatched from his home and set to work as a sled-dog during the Klondike Gold Rush. White Fang, set in the frozen tundra and boreal forests of Canada’s Yukon territory, is the story of a wolf-dog hybrid struggling to survive in a human society every bit as brutal as the natural world. This volume of London’s famed Northland novels also includes an early feminist story “The Night-Born,” and a pro-labor story “South of the Slot.” These works echo and enrich the themes of The Call of the Wild and White Fang with their unique emphases on the primordial, the instinctual, and the quest for social justice. London’s narratives in this volume focus on issues of continuing relevance to contemporary readers, including the value of the wilderness, animal rights, socioeconomic oppression, and gender inequity. This edition also includes an introduction by preeminent London scholar, Earle Labor, as well as a comprehensive biographical note on London’s life and works by scholar and executive coordinator of the Jack London Society, Kenneth K. Brandt.
