Take off the dress, Clara. You are not a guest here. You are payment." ​Clara Rossi’s life ended the moment her father signed his name on a gambling debt he couldn't pay. The price? Her freedom. ​She is dragged to the feet of Lucian Blackwood, the city’s most ruthless billionaire. To the world, he is the cold, calculating CEO of Obsidian Corp. To the underworld, he is the Capo—the heir to the Blackwood Mafia empire, whose hands are stained with blood and whose heart is made of ice. ​He offers her a choice: Become his wife for one year to secure his inheritance, or watch her father be destroyed. ​Clara signs the contract, thinking she can survive a marriage on paper. She thinks she is just a business transaction. But she didn't read the fine print. Lucian doesn't just want a wife for show. He wants a queen for his empire. ​The Rules were simple: ​Never ask about his "business trips." ​Never enter his private study. ​Never, ever fall in love. ​But rules are made to be broken. ​When Clara discovers a photo of herself as a child locked in Lucian’s private safe, she realizes this wasn't a random transaction. Lucian has been watching her for years. He didn't just buy her to save his company—he bought her because he is obsessed. ​And now that he has her, he will burn the entire city to the ground before he lets her go. ​A dark, possessive romance involving a hidden past, a dangerous mafia war, and a love that burns hotter than hell.
