The book is a good read, though could be written better. The central story of an emergency at a nuclear silo is used to hold the book together, but doesn't succeed as well as you might hope. That said, the details and the research into hundreds of incidents are fascinating. It leaves you surprised we survived the 50s, 60s, 70s, and 80s. This were a lot less under control than you might think. It's not just all the accidents with nuclear weapons, but also the faulty strategy of the day -- the all or nothing approach to nuclear war. Well worth the read.
