Jamie Kingston has been Brynn Chandler's best friend since middle school. Only once was their friendship tested—when Brynn gave Jamie a single kiss. Since then, they've had an unspoken agreement never to cross that line again, and she’s ready to let go of the past and move on.

But Jamie has loved Brynn for as long as he can remember, and now that he's ready to tell her, she has her sights set on someone else. Knowing this is his last chance, he asks Brynn to go on a two-week road trip. But their time alone brings old hurts to the surface, and Brynn has to decide if the one that got away lies at the end of the journey or if he's been by her side all along.
