The book is very well done, it reads like an action movie. More than that though, there's plenty of character development as well. Tracking the development and implementation of an anti-terrorism group called Rainbow Six, this has plenty of action sequences to keep you interested.

I've seen enough movies based off Tom Clancy's work involving Jack Ryan that you can really picture Harrison Ford in this book's role of saving the world from the evil's of terrorism.

The only real downside was some of the spins that felt out of place in the book. Two things stick out: It feels the author hates the author's hatred of Greenpeace and PETA is very apparent, though I won't complain about that too much. That and the author seems to have a few lines thrown in there, like "Jack knew this as only an insider does" that felt like there were in there to remind me of how knowledgeable the author is.

Speaking of writing styles, I found the story's exposition character very well done. All too often you find yourself following a stupid character for no other reason than having someone to explain something to. One of this books main plots follow Popov around, who was far from stupid, but enough out of his normal element that Clancy was able to use his ignorance to help explain some elements to us.

In the end, I thoroughly enjoyed this book. It was a refreshing change of pace from my normal science-fiction fare. I might have to try some of Clancy's other books.
