Jack London was born a working-class, fatherless San Franciscan in 1876, and in his youth was a boundlessly energetic adventurer. His adventures in the American wilderness and underworld informed his fiction, and his writing came to captivate the nation as it defined his era. Within his own short lifetime, London became the most popular and best-selling author of his generation. After a short, breathless life, he passed away at age forty, but he left behind him a glorious literary legacy. Award-winning author James L. Haley explores the forgotten Jack London-a man bristling with ideas, whose passion for social justice roared until the day he died. In Wolf, Haley returns Jack London to his proper place in the American pantheon, resurrecting the author of White Fang in his full fire and glory.
