The Wife Finder (The Billionaires of Silicon Forest Book 1) by Melissa McClone

He's about to get his first taste of failure, and she's about to break the rules. When it comes to love, all bets are off.   Self-made billionaire Blaise Mortenson made a wager to see who will be the last bachelor...but his plan to win could backfire when he starts to fall for the matchmaker he hired to find perfect matches for his friends.   Known for running her matchmaking business like a clandestine military op, precisely controlling every feasible outcome, Hadley's matchmaking success rate is unbeatable...but finding love for herself has been nearly impossible. There's no way her happily ever after could come in the form of a tech billionaire who isn't even looking for love...is there?   What should have been a simple business transaction quickly turns into something way more complicated, and Blaise starts to wonder if he's in danger of losing more than just the bet...
