Sunset Shimmer hasn't been to Equestria in a long time. Okay, she was there only a few months ago, but it was only for a moment, and she'd rather forget about that. One day, her friends manage to convince her to finally return, at least for the summer. After all, she could easily stay at Princess Twilight's. What Sunset soon discovers, however, is that there's a lot in Equestria that she doesn't know about, and when her feelings for her host come to surface, she finds this vacation might be more complicated than she expected.
