Phantom: Her Ruthless Fiancé - Ruthless Triad, #5

Pro-Tip: Don't agree to a fake engagement with a ruthless mafia crimelord like me after you catch your real fiancé cheating. I just might keep you. The final and most anticipated book in the Ruthless Triad series is almost here! She agreed to be mine for as long as it takes for a business deal to go through. She thinks this is a game. One she'll win if she plays by the rules. Here's what she doesn't understand.
When it comes to me, there are no rules. Scruples? Integrity? Playing fair? Nah. Our engagement might be fake, but she's about to find out.. I'm for real obsessed. There's nothing I won't do to make her mine.
