In terms of content, I might also suggest some titles which could be meaningful.  Zlata's Diary is a book about a girl writing during the breakup of the former Yugoslavia.  Freedom Writers is another example of a similar style.  In both books, the speakers or writers articulate what it is like to struggle in the face of social obstacles that seek to eliminate voice.  In both books, the authentication of voice is of critical importance.  If you are looking for more self descriptions of the Holocaust, the book, We are Witnesses is a book that has much in the way of relevance for you.  It is a collection of five teenagers' diaries through the Holocaust, of which Anne Frank is present.

Can you be more specific when you ask if there are other books similar to, Anne Frank: The Diary of a Young Girl? Do you want to know of more biographical or autobiographical works about young adults or would you like to know of more works written about the historical period of the Jewish Holocaust (1933-1945)?

Some works I can suggest about the Jewish Holocaust period are: Man's Search for Meaning by Viktor Frankl, Night by Elie Wiesel, The Sunflower: On the Possibilities and Limits of Forgiveness by Simon Wiesenthal, and The Short Life of Sophie Scholl by Hermann Vinke. These are some of the books I read in the various Holocaust- related courses I took in college. The last book is from the Jewish Virtual Library website. The works are about the life of an individual that lived during the Jewish Holocaust period of history. The works also serve as a reflection on the feelings the individual had at the time and/or after the events transpired.
