Sci-Fi Group Book Club discussion

In February 2017, I posted a topic about having themed group reads on a quarterly basis. To this end, I've set up another poll so that people could vote on a new theme for June. Once the theme (or themes if there is a tie) is picked, members can nominate books within that theme (or themes) for the next group read in a new topic. After a few days, members can then vote on which two books they'd most like to read in June in another poll.

The poll for this month's theme can be found here and will go live in about nine-and-a=half hours. I've used the suggestions from last year but I've also allowed write-in votes in case anyone feels there's a theme missing from the selection.
