Caught in a kill-or-be-killed mafia world, Leo fights the pull toward Marco—hate clashing with desire. As Marco’s sister Gia betrays her own to seize power, and new threats claw at their empires, Leo meets Ezra, a quiet werewolf stirring his heart. Torn between love, loyalty, and vengeance, can Leo break the oath—or will he find passion and strength in his sworn enemy?
