Years ago, I read Speaking Dreams by Severna Park, and I loved it.  Anyone know of any good lesbian sci-fi or fantasy novels or series?  I'm sure someone has made a list somewhere.

This looks like a great site for you to explore: http://lesbiansciencefiction.com/ ;)

I dunno if its on the link Adienne has, But I really liked Bending the Landscape.

There is an author, Gun Brooke, who writes lesbian SF

Try Melissa Scott.  She has a couple of SF books with lesbian characters.  Nicola Griffith does also (Ammonite and Slow River). 

Melissa

John Varley's Titan, Wizard and Demon. While not outright there is a strong hint that one of the main characters is a lesbian.

Solitaire by Kelley Eskridge.  Wonderful book.  Also a short story collection, Dangerous Space.

And in Wen Spencer's Okiah Oregon series, the main character has lesbian moms.

Periphery.  Erotic Lesbian Futures, edited by Lynne Jamneck.

Marion Zimmer Bradley's Renunciate Darkover novels: The Shattered Chain, Thendara House, and City of Sorcery.

Godmother Night, by Rachel Pollack

I'm gonna have to check out the sci-fi Bending the Landscape. I read the horror one and it was brilliant.

Ooooh, I'll have to check these out.  I've added them to my shelf on Goodreads.  I'm always looking for good horror short stories.

The Meadowlark Sings by Helen Ruth Schwartz.  Written awhile back, because the year is 2008, and that is the future.  Good book.

I have "Zeta Base" listed.  Not sure if it is enough Sci Fi for you or not. 

These are from this year's Lambda awards.  Under Fantasy/SF/Horror category.  Winner to be announced in May.  But the list always gives me books to look for.

• Centuries Ago and Very Fast, by Rebecca Ore (Aqueduct Press)
• Fist of the Spider Woman, by Amber Dawn (Arsenal Pulp Press)
• In the Closet, Under the Bed, by Lee Thomas (Dark Scribe Press)
• Palimpsest, by Catherynne M. Valente (Bantam/Spectra Books)
• Pumpkin Teeth, by Tom Cardamone (Lethe Press)

They have updated their website.  http://www.lambdaliterary.org/

Winners from previous years are under Awards, Winners and Finalists.

I just noticed a new lesbian urban fantasy at the bookstore.   Black Blade Blues by J A Pitts.  Did not realize it was lesbian until I got home and started searching for reviews. 

Oh.  Found out it is written by a guy.  Yep.

The Elemental Logic series by Laurie J. Marks is brilliant. Language like butter, and world that's just as developed as the characters.

I am a really big fan of Melissa Scott.  Trouble and her Friends is probably the most overtly lesbian of her books, but a lot of them, especially the later ones, have gender issues of various kinds as major themes.  Just got a whole bunch of her early books from the club.  I'm also a big fan of Marion Zimmer Bradley.  Most of her Darkover books have gender themes, including the Renunciate books, but the last ruler of the Comyn in the books is a gay man as well.

Saber & Shadow by S.M. Sterling and Shirley Meier.

I have a nice copy on my Bookshelf - no spine creases.
