Some of mine would be:
==Science Fiction==
H.G. Wells
Issac Asimov
Frank Herbert
==Fantasy==
Louise Cooper
Garth Nix
Neil Gaiman
Phillip Pullman
==Preternatural (or supernatural)==
Anne Rice
There are so many others.
Just to note: I had first thought of discussing Preternatural fiction in this group but have decided to leave it out for now. As there are a few other groups on preternatural already.
Still, feel free to list any supernatural authors if you like.
H.G. Wells, H.P. Lovecraft, and Douglas Adams.
Ooh yes, Douglas Adams. He's in my list as well. Thanks.
I'm a major fan of both Douglas Adams and Terry Pratchett, but my more 'serious' genre faves are probably Arthur C. Clarke, Neil Gaiman, George R.R. Martin and HP Lovecraft.
For all stories speculative in the genres Science Fiction and Fantasy.
If you'd like to share your own or discuss different styles, sub-genres etc, feel free.
PS: I start it, you keep the torch burning right? Also, there is the "The Techno-Fantasy Guild" group who also discuss science fiction and fantasy in a guild like manner. Here is their link > http://www.fictionaut.com/groups/the-techno-fantasy-guild
Cheers.
