What happens when that first spark is undeniable?

Pediatric oncologist Eva Monroe was finally heading for vacation in Puerto Vallarta to enjoy some much-needed rest, relaxation and sex. It was her goal to find someone to indulge in for the night—or the week, her choice.

Emergency room surgeon and member of Doctors Without Borders Grant Harrison is having fun during his time at the beach when he spies Eva and the heat between them slams into him with incredible force. After he approaches her, they end up going back to his room. What begins as a hot, intense encounter grows to more as they spend the rest of her time there together. Learning about each other and becoming close.

When they leave, neither want to end what they have started to build, but they're not exactly neighbors. They decide to try a long-distance relationship—she visits him in Arizona and he her in Iowa, but they want more. Who is going to be the one to give up what they have for the other?

Someone has to make a choice. But when it comes, will it be too late?
