SOLVED. YA Fantasy, main characters = middle school aged, Her name is EGG. She travels to a new world and ends up saving it. I think the people she saves aren't people - but I can't remember what kind of alien. There's a floating city too. [s]

(Egg isn't her real name, I think she chooses it for herself in the beginning of the first book). I feel like it's named something like "The flying egg" or "the adventures of egg" but no luck with those searches.
