This is the best book you’ll ever read about mixed martial arts fighting; and this will still be the case even if it’s not the first book you’ve ever read about mixed martial arts fighting. Kerry Howley’s debut is a riotously entertaining and piercingly perceptive account of the contrasting lives and dreams of a pair of Iowa-based fighters whose battles in the ‘Octagon’ become the vehicle for a philosophical treatise on the nature of glory.
