The Diary of a Young Girl by Anne Frank

The Diary of a Young Girl is a book of the writings from the Dutch language diary kept by Anne Frank.
During the Nazi occupation of the Netherlands Anne Frank began to keep a diary on June 14, 1942, two days after her 13th birthday, and twenty two days before going into hiding with her mother Edith Frank, father Otto Frank, sister Margot Frank and three other people, Hermann van Pels, Auguste van Pels, and Peter van Pels. The group went into hiding in the sealed-off upper rooms of the annex of her father's office building in Amsterdam. The sealed-off upper-rooms also contained a hidden door behind which the Franks would hide during the parts when Nazi soldiers were investigating the buildings for harbored Jews. Mrs. van Pels' dentist, Fritz Pfeffer, joined them four months later.
In the published version, names were changed: the van Pels are known as the Van Daans and Fritz Pfeffer is known as Mr. Dussel. With the assistance of a group of Otto Frank's trusted colleagues, they remained hidden for two years and one month, until their betrayal in August 1944, which resulted in their deportation to Nazi concentration camps. Of the group of eight, only Otto Frank survived the war. Anne died in Bergen-Belsen from a typhus infection in early March, shortly (about two weeks) before liberation by British troops in April 1945. (Summary by Wikipedia)
