Three books I enjoyed this year: this census taker, China Mieville To Say Nothing Of The Dog, Connie Willis The Possibility of an Island, Houellebecq If you enjoy science-fiction, it is quite possible that you wouldn't enjoy any of the books above or even classify them as science-fiction (I would though) -- so definitely look them up or try the kindle sample to see if they appeal to you. Also, I see Ann Leckie's Ancillary trilogy mentioned elsewhere, I second that recommendation. [Also, honourable mention to the TV show Westworld -- if it were a book I would have included.]
