I enjoyed the book for the most part, although I was left wanting more at the end. I kept waiting for there to be more to the plot. The opening sequence didn't seem to fit with the rest of the book, Vlad's story was incomplete or too glibly finished, and the setup for the climax (the two attacks) seemed rushed as did the climax itself (or should I say anti-climax). I wanted more about the school and the training, more development of some of the secondary characters like Thud and the UFO fellow or Thud's dad. In short, there was lots of potential, but a lot of it was left on the table.
