One of the best books that I have read in quite a while is Irmgard A. Hunt's On Hitler's Mountain: Overcoming the Legacy of a Nazi Childhood. The book was recommended to me by Barbara Kandel. It tells the story of a girl growing up on the Obersalzburg/Berchtesgaden during the Nazi era. The author gives a lot of insight into the average person's life in the 1930s and '40s. It is extremely well written, and is a quick read.
Anyone with an interest in this period will find it hard to put down.
