I think this book is a must for the understanding how the events evolved in those very difficult 13 days. The Author has made an excellent work in putting in a readable way hours of recordings that he himself heard over and over again. He did not fill any gaps but added the mood and the expresions of the word being said, and that greatly help to understand the situation. He also add parallel information of key events outside the recorded rooms and put all together in a very coherent form.
For us having suffered the chaos of the '60 as a collateral damage, knowing first hand what was happening in the Capital of the World is a revealing experience.
Also you can recognise the importance that the leadership had in both sides of the equation. The pressures, the uncertainty, the evident so called truth that a Leader has to overcome to find the right path in spite of them all is encouraging.
Hence I recommed this book to anyone who still want to know a great deal of the truth on the Cuban Crisis and learn first hand some excellent example of political leadership.
