The guest at tonight’s BSFA London meeting is NK Jemisin, author of The Hundred Thousand Kingdoms, its forthcoming follow-up The Broken Kingdoms, and the Hugo- and Nebula-nominated short story “Non-Zero Probabilities.” I’ll be doing the interview — so I hope to see you there, but if you can’t make it and have a question you’d like asked, feel free to leave a comment here.
As usual, the meeting will be head in the upstairs room of The Antelope: 22 Eaton Terrace, London, SW1W 8EZ. The closest tube station is Sloane Square, and a map is here.
There will be people in the bar from 6-ish, with the interview starting at 7. The meeting is free, and open to any and all — not just BSFA members — and there will be a raffle with a selection of sf books as prizes.

There’s also a Boris Bike stand on Eaton Gate, and a spider diagram for Sloane Square bus services can be found here: http://www.tfl.gov.uk/tfl/gettingaround/maps/buses/pdf/sloanesquare-2231.pdf
I hope it went well.
