As a young man, Jack London experienced firsthand what he later depicted in his adventure books: the struggle against the forces of nature, against seemingly insurmountable opponents and obstacles. However, his heroes never give up and grow from the challenges. The four volumes gather some of Jack London's best novels and stories for young readers. Alongside a gold seeker and a sailor, a dog and a wolf are the main characters in the volumes 'The Call of the Wild', 'The Sea-Wolf', 'Gold Rush in Alaska', and 'White Fang'.
