I'm The Mafia's Mistress

Isla Monroe never meant to fall for anyone, especially not him.
Luciano Moretti is everything she should avoid: cold, powerful, untouchable. A man whose name is spoken in hushed tones across the city. The king of the underground. The devil in a suit. And now, her stepbrother.
What began as tension turned into temptation. A look held too long. A touch that lingered. A breath stolen in the dark. One wrong move was all it took, and suddenly Isla is caught in Luciano’s dangerous web, where morality has no meaning and desire is a deadly game.
He tells her she belongs to him.
She tells herself she should run.
But there’s something about the way he touches her like he owns her. The way his voice dips low when she disobeys. The way the world fades when he’s near.
Luciano’s world is ruthless. There are no second chances. No happy endings. And yet, Isla doesn’t pull away.
She should hate him. Fear him.
But instead, she aches for him.
Luciano was never supposed to care. He built his empire on ice, on blood, on silence. But Isla is fire, untamed, defiant, and dangerously pure. Her innocence taunts him. Her curves tempt him. Her lips are the only sin he’s never had the strength to resist.
He wants to protect her, but he can’t stop breaking her.
She wants to escape, but she keeps crawling back.
What they feel isn't healthy. It isn't safe. It isn’t love.
But it’s real. It’s raw. It’s consuming.
And it will ruin them both.
She's his weakness. He's her destruction.
One forbidden night changed everything.
And now, there’s no turning back.
Some lines, once crossed, were never meant to be redrawn.
And some obsessions?
But can she really overcome the burns of the underworld?
