I'm always puzzled as to why, when people ask for great female science fiction/fantasy authors, her name doesn't come up; instead, they list Anne McAffrey, J.K. Rowling, Mercedes Lackey, etc ... (which I read as a child and enjoyed- but I'm an adult now and so were the people posting. Shouldn't you be reading more intellectual fiction?)
Also, at my local bookstore, they don't even carry anything by her. What's wrong with this picture? Why is she only read in high-school Literature courses? The way I just encountered her was just by randomly Googling a "Top 100 classic books" list.
