"Il richiamo della foresta" by Jack London is a novel published in 1903. Buck, a domesticated dog living comfortably in California, is stolen and sold into service as a sled dog during the Klondike Gold Rush. Thrust into the brutal wilderness of the frozen North, he must learn to survive through violence and instinct. As Buck adapts to his harsh new life, he gradually sheds his civilized nature and feels an irresistible pull toward something primal—the call of the wild itself.
