Last week, Nina Hunnicutt was a professor about to move into a gorgeous new apartment with her long-term boyfriend. Now, she’s single, unemployed, and living with her parents. Even more surprising is the fact that Quentin Bell, her childhood neighbor (and okay, fine, crush), is also back in town—and wants to resume the treasure hunt that ended their friendship almost two decades ago.

Hoping the reward promised to whoever finds the rumored riches left behind by the town’s eccentric turn-of-the-century seltzer magnate will help her get her life back on track, Nina agrees. Granted, last time the search resulted in a broken heart and seventeen years of silence. But Nina’s older and wiser now—surely things will be different.

Except, Quentin is also older and wiser…not to mention distractingly handsome. As they resume their hunt, Nina and Quentin begin to rediscover all the things they once loved best about each other. But unlike the treasure, the secrets that left them empty-handed the first time refuse to stay buried. If there’s any hope of finding what they’re looking for—and for a future together—Nina and Quentin will have to be brave enough to excavate their past as well.
