This book got me going from page one. A lot of people say that about a lot of books. But this book has an unbelievable ability to grab you and keep you. I was sweating from the first few minutes! The climax was totally unexpected. It left me literally out of breath. I've read thousands of books. Not many have this effect. While this is a technothriller, one thing I, as a woman, really liked was that it had good character development and a lot of humor. It made me care about the people, and about our country's future. It's patriotic, without being sappy or ridiculously macho. I've recommended it to dozens of people. I'm eager to see how the author will top this one with the rumored sequel! Get it and pass the word. This author's on his way up!
