This is not a book you would enjoy reading

I don't remember the context of the post and whether I expressed it in the post or in the comments, but somewhere several weeks ago I offered the opinion that future wars will not be decided by tanks and battleships or heavy bombardment, but rather by drones, autonomous weapons, and cyberattacks.  I cited this book, and this week I finally obtained a copy from the library.

Ted Koppel was a broadcast journalist, best known for hosting the ABC program Nightline for 25 years.  In 2015 he published this book, which details the susceptibility of the United States to failure of critical infrastructure, especially the national electrical power grid.  The opening chapter is an unrelentinlgy grim portrayal of what would happen if a large area of the country lost electrical power for more than a week.  In 2015 his concern was that such an attack could be accomplished through cyberspace, with the malicious actor breaching the poor or nonexistent firewalls around central power stations.  A second consideration was an electromagnetic pulse.  Nowadays a perhaps easier attack could be achieved by someone in the country unleashing a swarm of explosive-carrying drones programmed to attack substations, trunk power lines, and critical office buildings.  

Other chapters detail the inadequate response measures from civil authorities available in 2015 (and likely even less substantial now after the DOGE cost-saving cuts).  Additional chapters include interviews with various levels of "preppers," from ramen-noodle-saving suburbanites to rural underground-bunker-builders.

No practical solutions are offered, so it's basically about 300 pages of Gloom and Doom, which I just briefly browsed through.  It's a good book to know about; it's not a fun book to read.
