“The Chastisement of Your Peace” by Tracy Canfield
Canfield is a writer and a computational linguist who is fascinated by alien languages. (She speaks Klingon.) This is a really smart story about parallel worlds and multiple versions of the same woman. You can find her blogging at Alien Tongues. You can find this story online at Strange Horizons. Check out this interview with her from Lightspeed.
See you tomorrow!
