The Emperor’s Promise

He rules the underworld with an iron fist. She's running from a world that tried to destroy her. A promise binds them. A war will be waged for her survival. Jack is the emperor of the Chicago mafia-cold, calculating, and terrifyingly lethal. Born into bloodshed and raised without mercy, he's feared by enemies, respected by criminals, and worshiped like royalty in the city's darkest corners. He doesn't do feelings.
He doesn't do chaos. And he definitely doesn't do complications. Until Davina. Fiery, defiant, and fifteen years his junior, Davina is everything Jack despises-and everything he can't resist. When he pulls her broken body from the trunk of a car, Jack wants nothing more than to walk away. But an old promise ties their fates together. Now, she's under his protection, whether he likes it or not. She's a survivor, hiding secrets and scars.
He's a killer, bred for war. But when Davina's violent past resurfaces, threatening to drag her back into hell, Jack unleashes a side of himself no one has ever seen-possessive, brutal, and willing to burn the city to the ground for her. In a world ruled by loyalty, blood, and vengeance, one promise will change everything.
