"Daughter of Mettle" by Aaron DaMommio appeared in Daily Science Fiction on April 11, 2013. "You are a superhero about to be undone by your ordinary mortal daughter who craves your attention but whom you always seem to disappoint."
The idea of the ordinary mortal child of a superhero being peevish instead of proud of his or her super-parent is intriguing and refreshingly original. However, I found it difficult to get past the second person POV and confusing ending. Time travel might have been involved in the ending--which is a good idea, too--but it was not clear to me if or how. While certain allowances must be given when time travel is involved (the jumbling of past, present, and future can and should occur), the use of the device still must be clear enough for the reader to understand the story. 3 out of 7 rocket-dragons.
