Most of my science fiction is set in the same contiguous universe, although not necessarily at the same time and place, and rarely with the same characters. Stories published that are in the same universe:      Spheres      Concession Girl      The Ceiling Is Sky      By The Time I Get To Phoenix      Surf      Two for the Starry Night I also have a few more short stories in the works, a finished two-book series, and a third mostly-finished novel that are also set in the same universe. With luck, someday you will be able to read those as well. (At some point I may put more worldbuilding info here, but right now I'm busy writing. But hey, if you spot any massive continuity flaws in my works, please let me know!)
