White Fang and the Call of the Wild (Penguin Popular Classics)

"The Call of the Wild" is the story of Buck, a large dog who is betrayed, sold and cruelly forced to pull a sledge through the frozen Yukon. Buck must adapt to the brutality of his new life, until he is saved and domesticated again - although the call of the wild always persists. In "White Fang", a wild young cub, part dog and part wolf, grows up solitary and savage and becomes the most deadly fighter of them all, until at last he has the chance to respond to kindness and learn the ways of civilization.
