Best SF Novel of the Year

My vote for best SF novel of the year goes to Ninefox Gambit by Yoon Ha Lee. This is a brilliant if somewhat disturbing novel of the far-future, set in an interstellar empire in which calendarial and symbological science is so far advanced it is indistinguishable from magic. In addition to being the best SF of the year, it's also the best military SF for many years.
