I recently read "One Minute To Midnight" by Michael Dobbs. It is a new book on the Cuban Missile Crisis and supposedly has new information. The author claims that he accessed sources that were previously not accounted for, Russian soldiers, for example. Some revelations (according to the author) include the fact that the Soviets had nuclear cruise missiles deployed just a few miles from Guantanamo Bay, unbeknownst to US forces. The books also has a complete accounting of the U-2 flight that accidentally strayed over Western Russia during the crisis.
The book is thorough and very interesting to read. The dynamic between the different factions in the Kennedy administration is fascinating to follow.
My only real nitpick is that Dobbs constantly compares every nuclear device to the Hiroshima bomb. The is fine once or twice, but he over does it.
If you are interested at all in Cold War history, I recommend "One Minute To Midnight."
