Deep inside an underground fight club built on contracts, collars, and chemical obedience, boxer Siena Blaze is remade into the house’s most valuable weapon—and its next prize. Siena enters the program swinging, but every round costs more than blood. Jace studies her breaking point. Reign turns pain into discipline. And Kai, the silent handler who should be part of her cage, becomes the one danger she can’t stop watching. As the rules tighten and the stakes turn lethal, Siena has one chance to survive: learn the system from the inside before it rewrites her completely. But in a place where control is currency and desire is engineered, trusting the wrong man could finish what the program started. Dark, claustrophobic, and intensely charged, Ravaged in Ring delivers captive tension, underground combat, psychological power games, and a heroine who refuses to stay broken.
