Donner Let Her Go by Amelia C. Adams

Anna Holmes is stunned when her wealthy employer asks her to visit the Holliday Islands Resort to do some book shopping on his behalf. She’s never been anywhere so fancy before, and she’s positive that a country hick from Idaho like herself could never fit in with that kind of glitz and glamour. With some borrowed clothes and her boss’s credit card, she heads off on this new adventure, hoping she doesn’t embarrass herself in some large-scale way.
Like knocking over an entire display at the bookstore . . .
Donner Holliday was living the life of a secluded author on Puget Sound when he got the call to return home and take over a portion of his father’s resort. He wants to do a good job for his father, but he doesn’t want to give up writing, and he’s not sure how to juggle both. When he meets Anna Holmes, he realizes that his dreams aren’t complete, not unless she’s part of them, but their differences might be too great for them to overcome.
