The Girl In the Mirror, by Lev Grossman

The Girl In the Mirror is another story in Dangerous Women, and is a part of the author's The Magicians setting.  As always it's hard to judge a short story out of the context of its series.  But from this sample I get the feeling I've read it already--Harry Potter (there's even a shoutout in here)--so probably won't pursue it further.  It's kind of fun but there's a lot of references outside the story and just feels derivative now.  2 stars.
