We lost one of our great authors in January with the passing of Suzette Haden Elgin. I was privileged enough to meet her at WisCon in 2001, as you can see by the autograph. She was a Guest of Honor at WisCon in 1982 and 1986, long before I started attending. In addition to writing feminist science fiction, Elgin was also a poet, linguist, and non-fiction writer. I'm surprised Native Tongue didn't earn any major awards; is it too late to give Elgin a posthumous Tiptree? Learn more about her on Wikipedia, and buy her books here from Amazon.
P.N. Elrod was a favorite read of mine for a long time. I enjoyed her
Vampire Files series set in 1920s Chicago, but I lost track of the
series somewhere along the way. It looks as if she's become an anthology
editor and a hybrid author to boot. Find her at her website, Wikipedia, and Amazon.
Another former WisCon Guest of Honor making this list is Carol Emshwiller. I have two of her works (The Mount isn't pictured), but unfortunately no autograph. She is an excellent short story writer. You can learn more about her on her website, Wikipedia, or Amazon.
I know of Kelley Eskridge through her novel Solitaire, about a woman who endures a virtual solitary confinement. Eskridge is married to another SF woman author, Nicola Griffith, who will also be featured as part of this blogging challenge. Learn more about Eskridge via her website, Wikipedia, and Amazon.
Honorable Mentions: Phyllis Eisenstein and Anna Erishkigal, who was featured on the Blog Ring of Power.
