Science Fiction Book Club? Now with nomination request

The positive response to my post about Octavia Butler has me thinking that a science fiction book club would be cool. I have a few ideas for guidelines:

-given GT's diverse makeup, there would be an attempt to explore female, PoC and queer authors. However, lesser-known works by familiar authors and authors in translation would also be cool. (ETA I also would love to do sci fi works by those not known for sci fi, for example Jack London's The Scarlet Plague)
-personally, I would like to avoid series, although if we do do a series i could see doing the first one.
-no tie-ins! I know it would be fun to do a Doctor Who or Star Trek book, but... No.
-i would consider defining sci-fi loosely enough to include fantasy, horror and YA titles.

What do you think?

ETA It sounds like there's enough interest, so let's start nominating books! My first suggestion would be Kindred by Octavia Butler because I've already started reading it :)
