This is Jack London's companion piece to The Call of the Wild and is the story of the life of a dog who is mostly wolf. Set in the Canadian wilderness during the Gold Rush, the tale opens with his birth in the wild and subsequent deliverance to a Mackenzie Indian named Grey Beaver. We follow him growing from puppyhood among the Indians, through a career as a "fighting wolf" for a despicable owner, to his ultimate rescue by a kindly Southerner.
