Interesting, educational, terrifying - this book includes the ethics of science in war, cool spy secrets, and a chronology of bomb development that's pieced together masterfully. The chapter about the heavy water plant was my favorite. The brutality of war and the instability of our current nuclear situation is not sugarcoated. A few more thoughts a day later: I had to let go of keeping track of the many characters to enjoy this book. Also, I kept getting Sting's "Russians" stuck in my head all the time.
