Query: This book is a window into a young girl's heart!

"Anne Frank: The Diary of a Young Girl" is a very good book. I found it very well written, so well infact that I often forgot that it was written by a young girl around my age. In this book ,(or diary)that she named "kitty",Anne Frank pours out her heart. She tells"kitty" everything. She writes down her thoughts about the war, about her family and their secret hiding place, and most importantly, her hopes and dreams for after the war. This book is a window to a young girls heart. It has been translated into 31 different languages and over one million copies have been sold in hard-cover alone. If any book tells the honest fellings of a jew during the holocost , it's this one!
