Jack London 
White Fang [EPUB ebook] 

First published in 1906, ‘White Fang’ is a novel by American author Jack London — and the name of the book’s eponymous character, a wild wolfdog.
‘White Fang’ is the story of a wolfdog that is rescued from its brutal owner and gradually becomes domesticated through the patience and kindness of its new owner, Weedon Scott. 
‘White Fang’ was intended as a companion piece to ‘The Call of the Wild’ (1903), in which a domesticated dog reverts to a wild state.
As early as 1925, the story was adapted to film, and it has since seen several more cinematic adaptations.
