"If science is the story of the twentieth century, no drama is more compelling than that of "the Bomb" and its creators. But the tale of human conflict that connects the three scientists most responsible for the nuclear age - Robert Oppenheimer, Ernest Lawrence, and Edward Teller - was until now known only in broad outline.".

"Ten years in the research and writing, Gregg Herken's account is based on private papers, interviews with Manhattan Project survivors, and recently released documents and coded intercepts obtained from FBI and KGB archives and other sources around the world. One of Brotherhood of the Bomb's surprises is the complex game of spy versus counterspy that surrounded the bomb's building and later dominated the Cold War.

Yet, armies of U.S. security agents were unable to prevent the bomb's secrets from being passed to the Russians (sometimes by their American helpers). At the book's center is the question of loyalty - to science, to country, to family - and the wrenching choices that had to be made when such allegiances came into conflict."--BOOK JACKET.
