I would recommend this book as it views the trial and above all the defendants from a perspective which no other book can possibly offer. I think it important for future reader that they are aware that this is hardly a complete account of the trial itself. Other books (The Nuremberg Trial, by Ann and John Tusa for example) achieve this well enough. This book brings you into the cells and lets you hear what the defendants thought about the whole situation, until you become familiar with their different personalities. I would recommend reading some other book before this, to gain better knowledge of the trial, but definitely I would not miss this one. It'd be like reading a book first, and then having a chance to meet the actors.
