I'm very picky when it comes to audiobooks but the narrator was very understandable but I was able to listen to this audiobook my cochlear implant.

It is a very insightful book about Rober Oppenheimer and politics of the time. It provided in depth historical context into the Spanish Civil War, the reasoning why many people got involve in communism, world war two tensions, the development of the atomic bomb, the cold war, and the subsequent backlash against anyone who was tangently involved in communism.

My only criticism was some of book could've been better condensed. However, it's apparen that this book was very well researched.
