The Call of the Wild

London's 1903 novella follows Buck, a California estate dog pulled into Klondike sled-dog racing, as brutal experience strips away domestication and awakens something older and wilder. The narrative is propulsive and elemental, the naturalist prose still vivid after 120 years, and the bond between Buck and the kind prospector John Thornton carries genuine emotional weight — which makes Thornton's death hit hard when it comes. London's Social Darwinist worldview is visible throughout and ideologically dated in ways worth naming; the animal cruelty scenes serve the literary argument but are real and may disturb sensitive readers. Human characters beyond Buck's perspective are thinly drawn. For middle school and up, it remains a foundational text of American literature and a powerful story about survival, loyalty, and the tension between civilization and nature.
