Forget Me Not by Scarlett Andrews

Ever since high school, Sean Kelly has dated a certain type. The cheerleader type. As a star hockey player and the most popular guy in school, he never noticed Annabelle Keith, the frizzy-haired nerd who sat next to him in science class. But Annabelle sure noticed him.
Although a college knee injury ended Sean’s chances for a pro hockey career, he loves his job as a firefighter in the charming city of Golden Falls, Alaska. When he saves the life of a beautiful woman during a mountain rescue call on the treacherous slopes of Denali, something about her seems familiar … and everything about her seems sexy.

Annabelle, now a glacier scientist in the final year of her PhD, never forgot Sean. Seeing him again revives her old crush with an intensity that takes her breath away. But she’s already in a sort-of relationship with a fellow PhD student … plus she can’t quite believe that Sean, the boy who unknowingly broke her heart a dozen years before, would ever fall for her.

Brought together again, Sean and Annabelle rekindle what starts as a friendship, but quickly turns into a blazing physical passion that goes deeper than anything either have experienced before. But a saboteur is at work who will stop at nothing to destroy both Annabelle’s research and the couple’s newfound love.
