This was an extremely informative book that was well presented and narrated. It took me a long time to read, but that was because the subject matter was extremely depressing, so I preferred to take it in small doses and is not reflective of the author or the book. I usually try to avoid history books written by Americans because they are so centered on the U.S. a lot can get left out, I was very happy to find that was not the case with this book. This book looks at the invention of the atom bomb and its subsequent use as a world event, which it really was. Scientists from all over the world helped to develop it and using it of course changed things for everyone. There was a lot of detail and I learned everything I wanted to know without feeling like I was just reading lists of technical specs. I also thought the short chapters and the order things were presented in was intuitive and helped make sense of events that were happening all over the world. If you are looking to learn about the construction of the atom bomb, this is a good bet. The context in which these events took place is very well presented which I thought gave a well rounded view and tried to put things in some sort of perspective.
