So, if you're a member of the BSFA, you have one day left to nominate the best SF of 2017 for the BSFA Awards.
If you're not a member yet, consider joining? It's 29 pounds in the UK, and it includes the voting rights, a subscription to Vector, the magazine I'm now co-editing, and lots of other stuff. Oh, and you definitely don't need to live in the UK to join (although it is more dear if you don't).
(Personally, I haven't read much recent SF this year, so, idk. If you need reminding, there is a list of suggestions here that you can scan (and add to). I'll probably nominate Erin Horáková's 'The Bacchae' (on par with Euripedes' version) and Tim Maughan's 'Last Christmas' (almost as good as Wham!'s version) for short fiction. I don't really know if the Shadow Clarke Awards would be collectively eligible as a non-fiction entry ... maybe?
UPDATE: Confirmed, yes, eligible!
You know how I feel about awards).
