"Dark, Beautiful Force" by Jessica May Lin appeared in Daily Science Fiction on June 13, 2013. "You are a superhero, and your super-heroine lover recounts the story of your tumultuous relationship."
In general, second person POV does not work well, but this story reads a bit like a diary or journal, so it is not so in-your-face and actually kind of works. While the story does suffer a little from the cliches of superhero stories, it is nevertheless well-paced and entertaining. The ironic twist at the end was delicious. 5 out of 7 rocket-dragons.
