Lucian Vale didn't build The Black Ledger by indulging in weakness. Every escort, every contract, every client serves a purpose. And emotions? They have no place in his empire.Then Sienna Knight walks through his doors-a stunning, reckless, and utterly untrained temptation. Unlike the other women in his business, she has no experience in this world, no understanding of the power she wields. She's fire wrapped in innocence, too inexperienced to handle the kind of clients who come to The Black Ledger. If she's going to survive, she'll need guidance. And Lucian, against his better judgment, decides he'll be the one to train her.Under his instruction, Sienna learns the art of seduction, the rules of the game. He controls what she wears, how she speaks, how she carries herself. But as their lessons turn intimate-each touch more dangerous than the last-Lucian finds himself breaking his most sacred rule: never touch what doesn't belong to you.He tells himself it's just a test, just training. Until another man is set to claim her, and Lucian realizes there is no reality where he lets that happen.Because Sienna may be new to this world. But from the moment she walked through his doors, she was his.And if anyone else tries to touch what belongs to him: he'll burn The Black Ledger to the ground.
