Solid follow-up to the previous book, but I think that this book should have been a bit longer — so much more happened in this book than the previous one, but it's half the length! Or, both books could have been trimmed a bit and the whole duology could have been one, longer book. This book felt very rushed and the characters (especially new ones and especially villains) felt very flat and uninteresting.  Still, I'm not the target audience, and I would have liked this book as a teenager, so that's good enough for me.
