There's a great discussion taking place at The Book and Kitchen in London this Saturday.
It's called, Global Futures: On Science Fiction. Discussions on the ways in which Western ideals and narratives dominated the genre for decades, and how that is now being challenged.
(If my sources are correct, I hear Geoff Ryman will be there.)
