There's been lots of fantasy threads, time for a sci-fi one, I think!
I've just finished Ancillary Sword, the sequel to Ancillary Justice (by Ann Leckie). Not quite as good as the first one, but I still really enjoyed it. Would def. recommend both of them to anyone who likes traditional straight-down-the-line sci fi.
Now a little way into Ammonite by Nicola Griffith - liking it so far.
Anyone else?
