This summer I read "Bonhoeffer-Pastor, Martyr,Prophet, Spy"...Biography of Dietrich Bonhoeffer, a Lutheran pastor who became part of the German resistance against Hitler and Nazism in his home land. Excellent read!
If you are looking for a historical classic, read "The Hiding Place". My all time favorite book-the story of the Ten Boom family, especially Corrie, who hid Jews during the Nazi occupation of Holland and survived a Nazi concentration camp.
