Can three months, two planning projects, and a meddling grandmother finally make these high school hate crushes see just how right they are for each other?

Ambitious real estate agent Sinclair Buchanan is thrilled her childhood best friend has returned to their hometown and is marrying her first love. But the former beauty queen and party planner extraordinaire hadn't anticipated being asked to work with her high school hate crush, Garrett Davenport, to plan their mutual best friends' wedding. Five years ago, they spent one incredible night together—a mistake she won't make again. But when her plans for partnership in her firm require her to work with Rett to renovate his grandmother's seaside cottage, it becomes much harder to ignore their complicated history.

Rett returned to Holly Grove Island to celebrate the upcoming marriage of his two closest friends. And when they require a minor miracle to pull off their sprint to the altar, Rett feels obligated to lend a hand. But when his grandmother cooks up a scheme for him and Sin to partner on the renovation of her seaside cottage, he can't say no to the woman who sacrificed so much for him. So what if he's had a killer crush on Sin since they were teens and he hasn't been able to get their night together out of his head? He just needs to stay focused and stick to the plan. Then he'll head off on his next journey.

But when it comes to Sinclair Buchanan, things are never quite that simple. And this time, they just might discover how wrong they've been about each other and how right they are together.
