Ruthless Oath: A Dark Mafia Romance (Power and Blood Book 1)

Why we recommend it

Power and blood set the terms here, and a ruthless oath binds two people who'd sooner spar than surrender. This mafia opener trades in cold calculation thawing into reluctant heat, a hero whose loyalty is absolute and lethal, and a heroine refusing to be a pawn. Dark, tense, and threaded with vengeance, it's an inviting start for fans of dangerous men keeping promises no one should have made.
