When a young ex-Marine is found dead in a dumpster behind an abandoned auto shop, his body bearing the marks of days of torture and a bullet to the back of the head, J. J.'s autopsy tells a chilling story. A disciplined fighter living a double life. Hidden cash. And an underground fighting ring run by a ruthless kingpin who rules through blood and fear. As J. J. and Jack infiltrate a world of rigged bets, broken bones, and dirty money, they quickly discover that no one in this fight plays fair.
The deeper they dig, the more dangerous the game becomes, and it's clear that someone on the inside is making sure the wrong people stay one step ahead. With enemies closing in from every direction and more to lose than ever before, J. J. and Jack must go all in to bring justice before they're counted out for good.
