I've read many (but nowhere near all) of her books. I lost her trail right after reading The White Dragon around 1989. It took until I discovered The Ship Who Sang in 2005 or so for me to pick up her books again. I could swear I ran into her when I was still in attend-all-the-Cons! mode in college. Good times.
I did not know there was an animated film.
I think the best story I've heard regarding her is that, when a bunch of fanficfolk tried to tell her how her canon should be written (because they had embellished it during her writing dry spell), she gave them all a huge middle finger and wrote what she wanted anyway, tellnig them that it's her universe and she'll write about it however she damn well pleases.*
