Rogue Prince by Kylie Gilmore

Dylan:
I’m the crown prince of Villroy, but instead of taking the king’s throne like I should have, my father got us all exiled. I’d complain, but he had good reason. Now our once royal family lives in Brooklyn, and I’m about to inherit a new kingdom: my uncle’s construction business. It’s an opportunity to build my real estate empire and make something of myself. All I need is an experienced person to help take it to the next level. And then the girl who grew up next door to me—all woman now—shows up with just the business experience I need.

Too bad Ariana Bianchi hates me. I used to think it was undeserved—fallout from our families’ longtime feud—but there was this one time…

Ariana:
I’m newly divorced and crashing at my parents’ house until I can get my life on track for my ultimate goal of having a baby with the help of a sperm bank. It’s the reason for my divorce—he didn’t want kids—and at thirty-one the clock is ticking. So when the gorgeous pig of a man, Dylan Rourke, shows up at my parents’ house to ask me to work as a consultant for his company, I see an opportunity. He wants something from me? Yeah, well, I want something in return, too.

Only Dylan makes this way more complicated than it needs to be.
