Having just finished this series, let me preface my review by simply saying, buy this series!What an amazing series by an equally amazing author. I've been reading Bond's books for well over a decade, maybe two. I highly recommend all of this author's novels to fans of techno-thrillers, military fiction, etc. No spoilers in this review, but here's a very brief synopsis.China invades Vietnam to gain here food resources in a world gripped by climate changes that have left China reeling. The U.S.A. is isolationist, it's president unable to act overtly, racked by internal demons from his time as a POW in Vietnam, uses few advisers and assets to forestall Chinese hegemony over southeast Asia. And that's just the beginning!The series is wonderful. Buy them all and read them on order. You'll love it! You can thank me later for this sage advice! Ha!
