The author, Ms Muller, pieces together early parts of Anne's life (she was born in 1929) through letters and postcards sent by Anne to relatives, interviews with family members who survived the war, and access to museum archives. Her father lived over 30 years after the war. Several of Anne's friends are still alive as of 1/2014 ! There are sections that deal with Anne's thoughts about God, about her 10-12 yr old friends, about her kindred spirit with her father, about why relations with her mother were strained, about Peter Van Pels. There is background info on her parents family, which side was religious and which was not. There is even info on the last known contacts with Peter, Margo (older sister), and Anne - up to one month before she died in April 1945. I prefer this biography to the diary, because the flow form issue to issue is much smoother. There is section at the end of the book that deals with what became of many characters. The forward explains the author interest in writing about Anne. She is very humble and does not editorialize during her telling of Anne's story. It was a page-turner for me!
