The girl from our fanart Harry Potter Hermione and Book Sticker knows everything about magic, sometimes even better than teachers themselves. She knows every spell from all books in Hogwarts. When she is in doubt, she always goes to the library. Of course, that's all about Hermione Jean Granger - an English Muggle-born witch, a good and loyal friend of Harry Potter. If you don't know something or have doubts - call her, and she will solve your problems.
