For three years, Sierra Daniels has been scrubbing blood off the floors of The Crimson Cage, Las Vegas’s most brutal supernatural arena. Invisible… Obedient... Alive. In a cruel world where werewolf gladiators are forced to fight to the death for the entertainment of the rich and powerful. Sierra stayed alive by keeping everything secret, her wolf, her past, and the bloodline she should have lost when her family died fifteen years ago. But when a forbidden medical exam reveals the truth, her anonymity is shattered. She's an unclaimed Luna with Royal Alpha blood. Ryder Maddox, the arena’s undefeated champion, haunted by guilt, and just three fights from getting his freedom. He survived as a merciless weapon until he caught Sierra’s scent, and his wolf knew the one woman he was born to protect. His mate… His weakness… His next opponent. The owner of The Crimson Cage, a billionaire, wants the ultimate spectacle: fated mates forced into a deadly fight, broadcast live to millions. The winner earns freedom; the loser dies beneath the lights. But Sierra’s blood holds a powerful secret that could spark a rebellion. Ryder’s past is tied to the night her world was destroyed. The arena’s owner might have been hunting her for years. Now Ryder has to decide between the freedom he fought to earn, or accepting the fate Luna has tied to his soul. Sierra has to choose whether to keep hiding just to stay alive, or rise, as the royal her enemies failed to eliminate. When the cage shuts and the crowd roars for blood, can a damaged Alpha and a captive Luna turn their mate's bond into a weapon of freedom? Or will their love become the arena’s final kill?
