I've mentioned before that I'm going to be appearing at the Elgin Literary Festival this weekend as part of a speculative fiction panel. I've contacted my co-panelist, and we've come up with a list of topics for the panel. One of them deals with the various subgenres of science fiction/fantasy. I plan to talk about them briefly, but I'm not sure I want to list every single subgenre possible. I may find a list or diagram of the subgenres and share that with the audience.
When you think of science fiction or fantasy, which subgenres come to mind first? Time travel? Epic fantasy? Alien invasion? Feel free to share your thoughts in the comments.
