What are some good novels starring Morgan Le Fay?

I've read a few novels where Morgan Le Fay is a main character, the first was The Mists of Avalon, which got me hooked on the character. I am having a hard time finding others in the same vein. Are there any other novels that deal with Arthurian Legend that have Morgan Le Fay as the main character, but not as the evil conniving witch? I've already read "I Am Morgan Le Fay" by Nancy Springer, "Witch of the North," "I, Morgain," and of course "The Mists of Avalon" by Marion Zimmer Bradley. Are there any other good ones?
