Amanda turned down nerdy Preston's prom invitation a decade ago. And now she suddenly regrets it. When a grown-up Preston comes to her rescue in the most embarrassing situation imaginable, he has completely transformed... he looks like a god, fit to be Mr. December on his firefighter calendar. Now she's the nerd, and he's the sexy one. And he remembers how she treated him back when they were teens. Preston is quick to infiltrate her circle of friends, and she is forced to hang out with him all the time. Before she knows it, they're headed to Hawaii. This vacation isn't going to end well... but will it be because karma's back to get Amanda... or because she's falling head over heels in love?
