Rey bastardo de la jaula

Jax Carter, the bastard son of a disgraced housekeeper and a fight gym patriarch, secretly trains under three outlaw coaches. When he's entered into The Crucible, an elite, once-in-a-generation MMA proving ground, he must carry the weight of betrayal, shame, and thousands of pounds of hidden resistance training. As rivals rise and family tries to crush him, Jax must prove once and for all: he wasn’t born to break... he was built to fight.
