Le Guin is worth the read, Rodds. I read the
Earthsea books (they were a trilogy at the time) as a "Young Adult" (the category hadn't received that name yet), and enjoyed them. Found
The Left Hand of Darkness interesting some years later, and have several more in the infamous "To Be Read" pile.
Bobbo, maybe you just haven't found the stories by a female author that appeal to you yet? Beyond the Anne McCaffreys and Ursula Le Guins and those listed by Rodders are many many to be found. Sherri Tepper, James Triptree, Jr (yes, this was a woman, may she rest in peace), Margaret Weis, Melissa Scott, Kristen Britain, C.J. Cherryh, Robin Hobb, and Judith Tarr are a few I've read and liked (some more than others). Julie Bertagna, Madeline Howard, and Mary Hoffman walk these very Chrons regularly (possibly others I haven't had the pleasure to meet yet). Countless others, to be sure, and last but not least my personal favorite, Janny Wurts.
Just my personal opinion, but if I like how the story's crafted and the pictures it paints, that's where I find myself gravitating.
