"He was beaten (he knew that); but he was not broken. He saw, once for all, that he stood no chance against a man with a club. He had learned the lesson, and in all his after life he never forgot it." Jack London's most read book, The Call of The Wild, remains a timeless wilderness novel on the indispensible struggle for mastery and survival. Conflicts between the civilized and uncivilized worlds highlight the importance of primal instincts and the importance of belonging.
