Definitely fast paced. I read this book in just a few hours. However, if you are looking for a book with some realism in it, look somewhere else. Cliffhanger chapter endings, gun toting robots who revive dead soldiers, people with multiple chest wounds who survive, nuclear attacks, and way too clever criminal masterminds. It doesn't get boring, but it does make you say "Aw c'mon", more than a few times.
