Why does it have to be School??

So you come from another dimension and it's your 14th birthday. But your not excited, at all. You're sent to earth to get Star's wand because her family took it from YOUR family. You are a rebel and a punk girl and you do NOT want to do it, but if you don't then you'll have to go back to the "Princess Academy".
This is gonna be fun!! (note the sarcasm)
