I have really enjoyed this series and can't wait to read the third one. It is unique and interesting and I love all the moral dilemmas in it. Plus there is a scene near the end that reminds me strongly of something that would have happened in his Unwind series which is a series I happen to love. As much as I liked the first one, it was still kind of a "set up" where you are just familiarizing yourself with the world and the characters and now we can really get into the story. I enjoyed getting into the mind of the thunderhead as the author has added snippets of its thoughts at the end of each chapter. I highly recommend this series (as well as his Unwind series). The author is very good at seeing multiple sides of an issue and all the different ways that his world can effect people.
