EMP bombs are the main problem in the story and for the most part the power does come back but the chaos it causes in its wake makes a great terror weapon. Combined with some nifty tech that allows the bad guy to use remote viewing and actually take over a host then you have to wonder just who is controlling the bad guys. There is a new minor character introduced in this book and it is a bit refreshing to see someone that isn’t written as a super competent person as so many people in the DMS are. The bad guy is stopped in the end but the damage he does to the DMS and the government is pretty big.
