Best Novel shortlist:
The Windup Girl by Paolo Bacigalupi (Orbit)
Zoo City by Lauren Beukes (Angry Robot)
The Restoration Game by Ken MacLeod (Orbit)
The Dervish House by Ian McDonald (Gollancz)
Lightborn by Tricia Sullivan (Orbit)
The Windup Girl first appeared in the US in 2009 and in Britain in 2010. The Restoration Game and Lightborn have yet to be published in the US. Zoo City and The Dervish House were available in both the US and Britain in 2010.
Other categories are Best Short Fiction, Best Non-fiction, and Best Art. These shortlists are available at the BSFA website. The non-fiction category, curiously, has a novel and a podcast. The first time either has appeared in the BSFA non-fiction shortlist I suspect. I haven't read the "non-fiction" novel, Red Plenty, which has not been published in the US. The podcast, I can vouch, is worthwhile: Notes from Coode Street, which has been mentioned several times on this blog. The winners will be announced at Eastercon in April.
