I’ve read all of the 3-book series. The first book is most directly about the EMP effects. The second and third book delve more into the potential politics of recovery. Interesting POV but less about EMP and recovery from that specific attack. I highly recommend the reading as I do all of the “Enemies Foreign and Domestic” series by Matthew Bracken (FReeper Travis McGee). Stimulates all kinds of “what-if” thinking, a good thing, IMO.
