In this story Elphaba Thropp is thrown into Hogwarts by her father, although, he makes it clear that, and I quote, "I'm only sending you to this school to-" "I know, to look after Nessa..." While she's there, she'll first meet Luna Lovegood, who will become her good friend, Galinda Upland, who will become her enemy (the hatred is mutual), the Weasley twins, who find her to be an interesting character and hang around every once in a while, and many others as she stumbles her way through this story. But one thing is made clear on her journey; it's not easy being green. (A Harry Potter and Wicked crossover.)
