Billionaire Alpha Lucian Blackwood built an empire on unshakable control, yet he's a slave to the beast within and a past that forced him to swear off love forever. Architect Seraphina Wilder lives a life of logic and reason, never knowing she is the lost heir to a royal werewolf bloodline—a secret that makes her the most powerful pawn in a supernatural war she doesn't know exists.

Their fated meeting is not a gentle romance; it's a lit fuse. Hunted by a ruthless rival pack and haunted by a deadly curse that promises their love will consume one of them, Lucian and Seraphina are thrown into a battle for their very souls. To survive, they must unravel ancient conspiracies and defy an unbreakable blood pact with a terrifying elder race, where every choice could lead to annihilation.

In their darkest hour, they forge a bond more powerful than any curse, a love that rewrites the laws of magic itself. They emerge victorious, their souls united as one. But their victory comes at an unthinkable cost, unleashing an untamed power that rips fissures in the fabric of reality across the globe. Now, they are no longer just fighting for their love; they are fighting to save a world they inadvertently broke.

They have become the Sovereign, but in a world they have shattered, will they be its saviors or its ultimate destroyers?
