The Beast's Broken Angel: A Dark MM Mafia Romance (Once Upon a Sin)

He was meant to save lives. Instead, he signed away his own. Noah Hastings is a brilliant trauma specialist with a spotless reputation and a past he doesn’t speak of. When his sister’s life hangs in the balance, he makes a deal with the city’s most dangerous man—a decision that drags him into a world of blood-soaked secrets, brutal power, and a beast with a scarred face and colder heart. Adrian Calloway rules London’s underworld from the shadows, ruthless and untouchable. But the moment Noah steps into his life, everything tilts. Because Noah doesn’t flinch at Adrian’s monsters. He sees them. Names them. And worse—he stays. What begins as a transaction spirals into obsession, betrayal, and the kind of love that ruins men. But love doesn’t cleanse the blood. It only stains you deeper.
