C L Moore according to her entry on Wikipedia was one of the first women to write science fiction. Her Jirel of Joiry was also one of the first novels in the swords and sorcery genre and the first to feature a female protagonist. I have two books by C L Moore, Jirel of Joiry and The Best of C L Moore.
James Morrow is well known as a writer of satirical and apocryphal novels, the most famous being Towing Jehova and Only Begotten Daughter. I did have copies of these novels but they have gone astray – loaned to someone who never got around to returning them. So I’m left with the two sequels to Towing Jehova – Blameless in Abaddon and The Eternal Footman.
I also have two other of his novels, The Continent of Lies and The Last Witchfinder.
Another science fiction writer who deals with nanotechnology is Linda Nagata. I remember quite enjoying The Bohr Maker when I first read it, which obviously encouraged me to acquire Vast, about which I remember little.
Finally, the sole hard science SF book in my collection is Protector by Larry Niven.
Next – Pangborn, Pohl and Priest
