Jack London was born a working-class, fatherless San Franciscan in 1876. In his youth, he was a boundlessly energetic adventurer on the bustling west coast—by and by playing the role of hobo, sailor, and oyster pirate. From his vantage point at the margins of Gilded Age America, he witnessed such iniquity and abuses that he became a life long socialist and advocate for reform. 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 bestselling, author of his generation.

By adulthood he had matured into the iconic American author of such still-universally loved books as The Call of the Wild, White Fang, and Sea Wolf, but in spite of his success, he was at war with himself. The highest-paid writer in America, he was constantly broke. Famous as he was for conjuring the brutality of nature in story after story and novel after novel, upon the actual deaths of his favorite animals he would dissolve into helpless tears. Sick, angry, and disillusioned, 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.
