Crystal Prep Shadowbolt Sour Sweet was there when everything went down during the Friendship Games, and even helped save people from falling through the rips into the strange world of Equestria. But now she's entering that world herself as part of an exchange program. She has a new form and some odd hosts that she has to get along with.

A Manehattan couple answered a letter in the post asking for assistance with people from the other world, hoping to help the community. But now they've got a moody teenager in their home who's not even used to her hooves and wings. They've got to show her the best time possible, since they're representing their entire world. They'll need all their friends to help.
