You posted something similar on another thread. As I said there, how new are you? Do you know what magick can and can't do? Can you tell the difference between fantasy magic from fictional books/movies and real spiritual magick real life pagans use? Do you understand or did you simply find this site a week ago and haven't gotten much further? It's not a bad thing, so don't take it the wrong way. I have studied Wicca and magick for 10 years, in my year and a day I focused on my spirituality over spell casting, as a result my first 6 months I thought you could turn someone into a cat just because I didn't go farther than looking at the spells posted here. Once I began learning about magick I discovered the truth. Therefore I would hold off.
You say she likes vampires, anime and twilight, there's nothing wrong with that [except liking twilight] but if she cannot tell the difference between fiction and nonfiction, I think telling her 'magick is real, but you can't do any of the cool stuff you've seen on tv. Here's a book on meditation.' Might not end well.
