The Heir’s Enemy

By day, he’s my enemy. By night, he’s the only man I kneel for.

He doesn’t know my name. He’s never seen my face. He only knows I kneel for him, and that I’ll be back next Thursday.

In daylight, Adrian Valenti runs his family’s war for Bellwether’s waterfront: four hundred union jobs, a container terminal with his name on every page, and a father who has just given him thirty days to sell it all to the man who wants the Valentis gone.

On Thursdays, sealed in black neoprene on the Lower Floor of the Sanctuary, Adrian lets one man take control. A man in leather and gloves. A man with no name.

Gabriel Rourke is Victor Kane’s enforcer, the weapon aimed at everything the Valentis own. He has thirty days to break the heir. And he knows something about the night Adrian’s brother died that he has never told anyone.

Then Gabriel recognizes the man on his knees.

Now he’s holding the one secret that could destroy House Valenti. Keeping it from Victor is the first time he has ever betrayed his boss. It won’t be the last.

Two houses. Thirty days. One rule they’ve never broken: nobody unmasks anybody.

A note before you begin. The Heir’s Enemy is a dark M/M mafia romance for adult readers. It contains explicit sex and consensual BDSM (including rope bondage, full-body gear and hoods, dominance and submission, foot play, and denial), on-page violence and murder, guns, organized crime, the past death of a sibling, and parental betrayal. There is no dubious consent between the leads, no cheating, and a guaranteed happy ending.
