I haven’t read Sabriel, but I’ve read the others (except that I’ve only read Alanna of the Lioness Quartet).
Just about ANYTHING by Diana Wynne Jones. She wrote one novel for adults, that I know of, but for the most part she wrote YA novels. There’s a rape in Dark Lord of Derkholm, so you might want to put that one off for a few years. Jones could not write proper endings to save her life, but for the most part her stories are excellent reading for kids and adults, and many of her female characters are not traditionally feminine. My daughter is dyslexic, and had to struggle to read. She hated reading, but loved to be read to, so I read to her every night. When she got too old for little kid books that could be read aloud in a matter of minutes, I started to read longer books, a chapter per night. She got so involved in the stories of Jones, though, that she decided to give pleasure reading a try. She had her problems, but she learned that she COULD enjoy reading. And this is because of Diana Wynne Jones’ abilities as a storyteller.
The Tiffany Aching books are very good for everyone, no matter the age. So is The Amazing Maurice and His Educated Rodents. Pratchett will sneak philosophy into his YA books, to get his young readers to think. Of course, he does the same thing with his books for older readers, too. Good Omens might be a bit too advanced for her right now, but buy a copy and have it available.
I just read Alanna a couple of weeks ago. I found it to be rather predictable, and I probably won’t read the rest of the series, but my 10 year old self would have eaten it up.
The Blue Sword and The Hero and the Crown are both excellent for her. Both stories have a little romance in them, but it’s of the undying love version, not the steam up the windows version.
Lawrence Watt-Evans has a series of Ethshar novels and stories. For the most part, these stories can be read in any order, though books will occasionally reference characters and occurrences that happen in other stories. If you have a choice, get them in chronological order. She’s too young for the Brown Magician series, and the Annals of the Chosen are best avoided by people of all ages.
When I was that age, I lived to read the next Andre Norton book. I also read a lot of Heinlein juveniles.
