Ninefox Gambit is sci-fi. I bought my copy new.
Review:
This takes place in a far future world where people's belief systems and the calendars they agree upon can somehow affect the physics behind how everything works. All the action is centered around a place called the Fortress of Scattered Needles, which has been taken over by rebels following a heretical calendar.
Captain Kel Cheris of the hexarchate has recently fallen into disgrace for her unconventional tactics. The situation at the Fortress of Scattered Needles gives her a chance to redeem herself, although she almost immediately comes to regret her proposed solution, which involves allying herself with the long-dead tactician Shuos Jedao. Jedao was widely regarded as brilliant, but he was also a madman who, in the end, killed both friend and foe alike, and Cheris had no idea that his "resurrection" would involve tying him to her mind and body. It's not a comfortable position to be in, to say the least.
