The Tenacious Billionaire - Knightly Encounters, #1

In a dating culture obsessed with swiping, Gavin Lockdale still knows the art of sweeping. He is determined to convince Liza Banks that just because he's rich, he isn't necessarily bad. In fact, he just might be the best she's ever had. Liza is grateful to Kate Knightly for rescuing her from a bad first date, until she finds out Kate is an elite matchmaker who has been hired to bring Liza to a fundraiser at the home of a young billionaire.
One erotic night with Gavin, which might have been a mistake, though it will likely never be a regret (for either of them), is not a basis for starting a relationship. Liza is more than happy to relegate the encounter to her One-Night-Stand file, but Gavin's negotiating skills are strong. He's a closer and he's at the top of his game. But can he seal the romance deal with Liza?
