First, let me tell you a little about the book. This series follows Net Force, a division of the FBI set up to deal with net crimes in 2010. CyberNation deals with a group trying to form a nation based completely on the net. Their main goal throughout the book is to get more people to sign up with them, so that they have the numbers to get the attention of current nations. To get people to join, they disrupt the internet, in a not very legeal way, and so Net Force is called in. The rest of the book is Net Force trying to catch the hackers doing the disruptions.
In general this series has a very well thought out discription of what needs to be done to protect and police the net. Having said that, I have noticed that the Net Force books have been going down hill, and this one continues that trend. A lot of time is spent on character development, but no development actually comes out of it. For example, we see Jay Gridley question his upcoming marrage. But in the end, the final decision has nothing to do with the pages of inner questioning that he goes through. Then there is the introduction of new 'toys' for the military, that never show up again. Add to that the fact that every other scene leads to sex, and that there is almost no technology discription, this book is only a shadow of Clancy's work.
IMHO this series has become a soap opera, with most of the time spent on generic character development and sex, and very little time spent on the action and discriptions that brought me to Clancy in the first place.
