The Call of The Wild & White Fang

by Jack London. 

Buck, the dog, is snatched from his pleasant life on an estate in California and taken to the turmoil of the Klondike gold rush. "He had been suddenly jerked from the heart of civilization into the heart of things primordial." 

This is a wonderful book that grips you from the get go. Published in 1903 it was an almost instant success and it's not hard to see why. It cracks along at a great pace and draws in timeless themes of humans and the environment. No surprise this continues to be a well-known classic. 

This is a paperback edition in good condition.
