King Of Sin (en Inglés) - Monroe K Noah

He built his empire on power, silence, and the ruins of anyone foolish enough to stand in his way.
Damien Voss does not lose. He does not bend. And he absolutely does not fall.
Until her.
Marian Ellis has spent her entire career becoming untouchable. Sharp. Fearless. The kind of woman who walks into a room and changes the temperature without trying. When she takes on the most dangerous case of her career, she is prepared for a difficult client.
She is not prepared for a man who looks at her like she is the only unsolved problem he has ever wanted to take his time with.
What begins as a professional arrangement unravels fast. He provokes her. She refuses to flinch. He watches her like she is something he is trying to memorize. She tells herself it means nothing.
She is lying to herself.
But underneath the tension and the late nights and the charged silences that say everything neither of them will, Marian is sitting on a secret. A discovery buried inside the case files that connects Damien's empire to the worst night of her family's life. A thread that, once pulled, could unravel everything they have been carefully, dangerously building toward each other.
He is not a good man. He told her so himself.
The problem is she is starting to believe he could be. For her.
And that is the most dangerous thing she has ever let herself think.
King of Sin is a steamy, slow-burn billionaire romance about power and the people brave enough to see through it. About desire that builds until it cannot be contained. About the secrets we bury in the foundations of everything we build, and what happens when someone we love finds them.
For readers who want their billionaires complicated, their heroines unbreakable, and their love stories hard-won and completely worth it.
Warning: This book contains steam, emotional gut punches, and a hero who will ruin you for anyone simpler.
