My 1st published fanfic on the interwebs. OC and Rarity - not shipping. Although it has the potential to be :3

Plot in a nutshell (*Spoilers*)

Rarity's brother, Starflash, returns from his exile. Rarity begins to freak out about preparations and parties - only to find her situation gets worse and worse and then Applejack digs her a hole to sit in (metaphorically, obviously). It all turns out ok in the end and Rarity is happy to be reunited with him.
