Okay, time for the "big one." (No, not novels. I barely read any novels released in 2015 and of those few I'd only recommend one, so no post for them.) If you haven't already, here are my posts about novelettes and novellas. And I'd be remiss to not point out that I have an awards eligibility post please read it please love me. Anyway, on to the stories!
This category always has the most things to consider, so even more than any other category, this is just basically "stuff I really liked/stayed with me" rather than "the best." I also tried to pick stories that I think have been more overlooked than others, not that there aren't good reasons for some stories to go viral, but I prefer to signal boost more obscure work. (And I still wish there was a flash category in Nebulas/Hugos. There's SO MUCH flash being published now, but flash would have a hell of a hard time getting nominated. It's different enough from short stories that I think there's a need for the category. But that's a post for another time, or more likely, never.) Nine stories, online links where available:
