Download the book Jack London died at the age of forty. In this autobiographical work, London describes his life as seen through the eyes of John Barleycorn (alcohol). There is much controversy about the cause of his death just as there is about alcoholism and addiction. London's brutally frank and honest analysis of his own struggles and bouts with alcohol was way before its time and more modern theories of addiction. With remarkable candor and insight, London describes the demons and gods he encountered through both friend and enemy, John Barleycorn.
