In this darkly funny work of literary nonfiction, a bookish young woman insinuates herself into the lives of two cage fighters — one a young prodigy, the other an aging journeyman. Acclaimed essayist Kerry Howley follows these men for three years through the bloody world of mixed martial arts as they starve themselves, break bones, fail their families and form new ones in the quest to rise from remote Midwestern fairgrounds to packed Vegas arenas.
