I really enjoyed this book. At the very beginning of the book, I felt like some of the characterization was a little forced, or possibly just done in too calculating a method. However, that's only within the first few chapters, and after that the individual voices of the characters were clear enough that I forgave the earlier issues.

The plot is tense and moves forward at a quick pace, as any great thriller should. The ideas behind this story are both fascinating and terrifying, the latter because the technology described in the book currently exists. In fact, the technology is so current, I almost hesitate the place the label science fiction on it.

My only real issue with the book is the abruptness of the ending, which does not resolve nearly enough of the sub-plots. Apparently, there is a sequel being released next year, titled Freedom TM, which explains why so many parts of the story are left unresolved. I've read that this book was originally at least twice as long, but he was asked to split it into two books for publishing, which makes sense, and is the only reason that I'm taking off one star.

This is an excellent read, and helps to shed light on just how vulnerable we have made our society by using homogeneous and centralized networks.
