The Madness Underneath  - Maureen Johnson

I finally got an arc for book 3 (Yippee and thanks to Kathy!)  But reading for a whole bus and train ride to work was enough to convince me I had no idea what was going on and I had to go back to the beginning of the series and start all over again from book one.  So here's to hoping book two is as good as book one was.  I really enjoyed it the first time through and I'm super excited to finish the rest of the series!
