The preliminary list of women science fiction writers: go down the list and bold those writers whose work you know you've read, and list the most memorable or significant-to-you work(s) by that writer that you've read (or put "all" if the writer's that good!). Italicize those writers whose work you've tried to start reading, but have bogged down, stopped, or not gotten to it for whatever reason. Strike through those writers whose work you've read and just can't stand. And add # for works you used to love and now hate.
I like some Atwood (Cat's Eye, Alias Grace) but don't think of her as an sf writer.
Marian Zimmer Bradley
I like the Darkovers, especially the Amazonian ones. Get a bit tired of all the posthumous ones, and stopped reading.
Lois McMaster Bujold
I have enjoyed almost all of her works. I think I like the Vorkosigans the best - especially Memory and Mirror Dance. The romantic in me liked the latter Miles romantic ones.
My personal favourite is Finder. Also liked War For the Oaks
Suzy McKee Charnas
I've had trouble with her, for some reason.
The Hidden Land books irritated me, and Tam Lin went on just a bit too long, but I loved Juniper, Gentian, and Rosemary
I've read all the Wizard books - find them entertaining but not earth-shattering.
Suzette Haden Elgin
Charlotte Perkins Gilman
Of course, "The Yellow Wallpaper" - I teach it and think it's brilliant.
Love her. Haven't read one of hers that I haven't liked, but I have a soft spot for the Silicone Mage series.
Nina Kiriki Hoffman
Have only read the most recent, but liked it a lot. Should investigate others.
Diana Wynne Jones
Just adore her. My favourite is Fire and Hemlock, but I also love Howl's Moving Castle
Read and quite enjoyed the first series, but got bored.
A fairly recent discovery. All are enjoyable, think Thomas the Rhymer is particularly fine.
Guilty pleasure. Guilty pleasure. Guilty pleasure. Particularly liked the first series, "Arrows of the Queen"
I loved her early stuff: Don't Bite the Sun, The Silver Metal Lover. Others are very uneven and unpredictable.
I actually like her Y/A non fantasy, especially The Young Unicorns and The Arm of the Starfish and Dragons in the Waters. Sometimes too preachy.
Ursula K. LeGuin
A Wizard of Earthsea was a seminal book when I was young. Left Hand of Darkness amazing. She's one of my quintessential writers. Love her. (I adored Tehanu, too)
Have read, but don't really remember any of them.
A very interesting and innovative writer. The first that I remember to really introduce gay sexuality.
The angel ones made me cry (mostly about the dog)
Was quite impressed at first, but got bored with her writing the same book over and over. Liked the Harper Hall ones the best.
Have read all. The Riddle Master trilogy is one of my desert island books.
All are terrific. Absolutely adore Deerskin, even thought it's probably the toughest of them to read.
She was one of the first sf writers I ever read. Found her less fabulous later in my own life. Year of the Unicorn is a personal favourite.
Woman on the Edge of Time, but also have enjoyed her non-sf novels.
Have read all, but am unconvinced.
Frankenstein is wonderful
Sherri S. Tepper
Uneven, but almost always readable. Grass is a pure and perfect novel.
James Tiptree Jr.
Joan D. Vinge
I've only read The Snow Queen
I think I've read her, but don't remember.
Domesday Book is another pure and perfect novel. Have liked almost everything. Lincoln's Dreams haunts me.
Well, of course.
