Having recently finished a biography on Dwight Eisenhower, it was interesting to see WWII from the perspective of the Allies and a German. This book gives you a greater appreciation of the German people who were oppressed, while also giving you an even greater distaste for those deeply involved in the S.S. The biography also will give you better insight and more appreciation of Bonhoeffer's other works, particularly The Cost of Discipleship
If you are going to read a biography soon, this is a good one. Bonhoeffer's story will challenge you in your faith and stretch you beyond a way of life that can easily become all too comfortable within the States.
