I just read Kiji Johnson's excellent 2009 World Fantasy Award winning short story in World Literature Today:
26 Monkeys, Also the Abyss
You can also listen to a reading of it:
and, if you like it as much as I do, you might want to read Juliette Wade's ridiculously close reading of the story
then, if you are feeling very adventurous, check out her 2010 Nebula Award Winning short story "Spar"
