This was a fantastic tale of how a foreign power might attack the United States. Great attention to detail was maintained by Mr Austen. Reference was made to an old Civil Defense shelter in New Orleans. In the mid 1960's, I spent many hours at that location. The descriptions and diagrams were rock solid. The discussions of the SCADA vulnerabilities are real - and evidenced by the real world Stuxnet virus recently unleashed on Iran. I LOVED it !
