Fangirl

Well done story in the mind of a girl...coming of age in college-dealing with all of that + she's a twin...with challenging family dynamics.

Here's the kicker - if you are going to read the Simon Snow series (and you should) —- read that first. This book's POV character writes fan fiction for a fictional series set with the same characters in the same world but also will spoil some of the joy of the discovery in the series.
