Reckless Heir by Elle Kay

He wrote her name in a file eighteen months before she knew he existed.
Mine, he noted in the margin. He told himself it was strategy.
He lied.
When her brother sells Sofia Conti to settle a debt with the Bratva, she arrives at St. Gabriel University with a blood oath on her lips, a barcode sewn into her collar, and exactly one plan: survive Aleksei Mikhailov.
He’s everything the rumors promised — cold, controlled, lethal in a suit. The heir to a criminal empire. A Formula 1 driver who treats speed the way he treats everything else: as something to master and move past.
He isn’t supposed to be this.
Aleksei doesn’t want. He acquires. He engineered the debt. He arranged the contract. He built the entire mechanism that placed Sofia inside his orbit — then watched the mechanism break down the moment she looked him in the eye and said don’t be late to dinner.
Now they’re sharing a Tower suite inside Obsidian’s gothic fortress, and Aleksei is running out of ways to classify what he’s feeling under irrelevant.
Sofia is starting to understand that the man who bought her has been falling since the night he kept one photograph out of fifty-four — the one where she was laughing in a courtyard and had no idea anyone was watching.
He thought he wanted an asset.
He wanted her.
The problem is she knows it. And she hasn’t decided yet what to do about it.
