Cornered at her father's funeral by her treacherous fiancé Vincenzo—who poisoned her father and forged a will to steal her $10-billion trust—heiress Serafina flees to the heavily guarded manor of Domenico, the untouchable global mafia king. There, she stumbles upon his darkest secret: Domenico carries an ancient Alpha Werewolf curse. With a gun to her head, Serafina kisses him desperately, biting his lip and accidentally triggering a life-and-death blood pact that binds their fates.
They strike a ruthless deal: by night, she is the only blood source that can calm his raging curse; by day, he is her unstoppable backer. While Vincenzo foolishly mistakes her defiance for a game of hard-to-get, Domenico’s possessive favoritism shields Serafina as she ruins her enemies at a high-society gala and strips Vincenzo of his stolen power. When a dark magic trap triggers, Serafina risks everything to save Domenico, breaking the curse and revealing she is his one true fated mate. Transforming into his lethal wolf form, Domenico purges the traitors and lays his entire empire at his new Queen's feet.
