The best short story, novelette, novella, and novel all went to the nominees that I voted for. Best short story went to The Water that Falls on you from Nowhere by John Chu. Best novelette went to The Lady Astronaut of Mars by Mary Robinette Kowal. Best novella went to Equoid by Charles Stross. Best novel went to Ancillary Justice by Ann Leckie. All were excellent stories. I think my favorite of these winners was The Lady Astronaut of Mars.
Ancillary Justice was kind of military SF, which I'm not normally all that big of a fan of, but it incorporated some concepts that made it really interesting, including the main character who was a ship with intelligence and multiple ancillaries, reanimated dead people who are linked to the ship and serve as a sort of security force, and serve as an extension of the ship's intelligence. The main group of people in the book also don't differentiate between genders, and always use the feminine pronouns for both males and females.
Equoid was an extremely creepy story about unicorns, but not your normal unicorns. They are Lovecraftian horrors! It was also fairly humorous.
I only vaguely remember The Lady Astronaut of Mars and The Water that Falls on you from Nowhere. I don't really remember the details well enough to do descriptions, but certain parts are stuck in my head.
In other categories, Gravity won best dramatic presentation long form, which kind of annoyed me since it wasn't really Science Fiction or Fantasy. In best dramatic presentation short form, the Game of Thrones episode The Rains of Castamere won over all of the Doctor Who episodes and related specials. Lightspeed Magazine won best Semiprozine, SF Signal Podcast won best fancast, and Ellen Datlow of Tor.com won best editor short form.
