Book excerpt: Born in the wilds of the freezing cold Yukon, White Fang – half-dog, half-wolf – is the only animal in the litter to survive. He soon learns the harsh laws of nature, yet buried deep inside him are the distant memories of affection and love. Will this fiercely independent creature of the wild learn to trust man again? Richard Adams, prize-winning author of Watership Down, introduces this chilling, beautiful tale of the wild.
