Demonglass by Rachel Hawkins

This is a continuation of Hex Hall.  After discovering her powers, and what kind of trouble they can get her in, Sophie decides to go through the Removal.  This will make her normal, and she won't have to worry about using her powers for evil.  Before she goes through the process, her father wishes to talk with her about doing this.  However conversations stop when The Eye begins looking for Sophie in London.

Continue the saga, and (spoiler) it looks like there is another book on the way.  If you haven't read Hex Hall, check out my blog review and my shelfari for information about Rachel Hawkins and her books.
