Jack London & Pocket Classic 
White Fang [EPUB ebook] 

Considered both a companion and mirror to The Call of the Wild, this stirring adventure of friendship and survival reveals the conflicts between domesticity and instinct, as well as society and the natural world.
Wronged by human and beast alike, White Fang has endured through brazen ferocity. An enemy of his kind, he is sold to a dogfighter who pits him against other canines to the death—until a Yukon gold hunter comes to his rescue and provides an opportunity for a new life. As the wolf in White Fang sleeps, kindness and compassion allow him to understand what it means to be in the confidence of man.
