Voting for the SFX Awards 2013 is now open. One of the categories you can vote for is Best Novel.
50 titles are suggested, including a couple of Steampunk novels (Lavie Tidhar's The Great Game and Cherie Priest's Boneshaker), but any title published in 2013 is eligible.
Pax Britannia: Time's Arrow was published in 2013. Just saying.
