When life hits him hard, Joe Carman punches back. Newly 40, Joe juggles long hours working in a boiler room, an ongoing custody battle, his wife's chronic illness, and the demands of raising four girls. The one place he finds release is in the ring, where he competes in the bruising sport of mixed martial arts. Despite the promise he made to his family to stop fighting, Joe continues to train secretly, determined to prove that he can keep up with the new crop of younger, up-and-coming competitors. But as he contends with a series of increasingly worrying health scares, the question arises: how much is Joe willing to risk—his family, his marriage, maybe even his life—to keep fighting? A true-life tale of resilience that unfolds with all the drama of fiction, The Cage Fighter is a riveting look at the demons that drive a man to push himself to the limit.
