This book would be a great spy film! This well-crafted version of the race to build the ultimate weapon is based on exciting scientific discovery, espionage and war drama. As World War II and a small experiment demonstrating fission rock the status quo, several characters’ involvement deepen. Readers follow: Harry Gold, the spy and schmoe in Pennsylvania reluctantly(?) working for the Soviet Union; Oppenheimer, the nutty professor and scientific genius with his humongous, secret team of geniuses; and Knut Haukelid, the Norwegian resistance fighter. While the race for the bomb was exciting, the book deals with the destruction and arms race matter-of-factly. Some pictures and bibliography are great enhancements to the book.
