Luca De Santis, a ruthless mafia underboss who fixes problems permanently, steps in when he notices the irregularities in her files. What starts as oversight quickly turns into interference, then protection, then something far more dangerous. Because Elena isn’t just in trouble. She’s been found by it. And Luca doesn’t leave loose ends behind… unless he decides to keep them.
