If she's into bodice-rippers, you could always get some Barbara Cartlands for her. They're basic "pills and booze" (Aussie euphemism for romance publishers Mills & Boone) but the girl is ALWAYS a virgin until the wedding night. Although in my opinion you do need to be either very young or a certain level of brain dead to read too many of these. I have had my moments when they were all I could handle... but watch out for romance novels in general, they can get a bit rough.
The thing these days is to be fairly graphic, unfortunately.
Other thoughts - L M Montgomery's books might be good for her. I wouldn't discourage her writing, it's a tricky one.
An author I can heartily recommend as being stimulating for a budding writer as well as very entertaining, but very clean (apart from mentions of muck, etc) is Terry Pratchett's "Discworld" books. You'd probably enjoy them too. A good one to start with would be "The Truth" (about the first newspaper on the Discworld) and "Soul Music", about a rock band and commercialism. The books have magic in them as well as politics but are very entertaining.
Or the witches ones - "Wyrd Sisters" which is like Macbeth but form the witches' point of view, followed by a couple of other books on a different theme.
Or books written for children - I would really recommend the Tiffany books (also set on Discworld) because Tiffany is a little girl with a different way of looking at the world. She has a little brother who she doesn't like very much because he's so sticky. But when the Queen of the fairies kidnaps her brother, Tiffany goes after him. He's HER brother, he doesn't belong to anyone else. Besides, their mother is crying...
There are three books already in the Tiffany series, each book stands alone but follows well from the previous one.
It's similar to Harry Potter, but not so bleak I don't think, and far more intelligent. And at times very funny.
There is a scene in the first book where Tiffany goes to a fair to buy some intelligence. She asks to learn something about palaeontology and the travelling teacher says to her, "Now THAT's a big word for a little girl."
Tiffany replies, "Not really. 'Patronising' - THAT is a much bigger word."
I always made a point of reading the books my kids were reading, so I could discuss the books with them. Even if I didn't like the books, I did my best to read them so I could discuss the books. If I didn't like the morality I said so, but the deal was, we discuss the literary merit of the books and often the morality isn't as relevant. A book can be highly moral and badly written; or brilliantly written but very immoral. For example, "Story of O" is beautifully written but I just can't accept the level of female subjugation in it, I find it immoral.
Good luck with this one.
