Bluebell Berry attends Canterlot High and is living an ordinary life with friends and a boyfriend. That all changes one night when she accidentally finds herself in the Crystal Empire surrounded by guards. Forced to stay as a pony for 30 moons, Bluebell must learn how to be a pony and figure out what to do. A helpful guard may just be able to be the guidance she needs over these long weeks. Unfortunately trouble may be brewing in the north, grudges left unchecked will cause a dangerous game to begin for the Crystal Empire. Can they defeat this growing threat? And will Bluebell ever be able to return home? Will she ever want to?...

Note: Sunset Shimmer never happened in this so no one from Canterlot High knows that there is a portal to Equestria. (hense the Alternate Universe tag)
