Diary of Anne Frank Intro

Honestly I'm just reading this because I can't decide on a short enough non-fiction book. I'm almost anticipating this to be an easy read simply because I remember  elementary school having this as a book to read. Although as older person, it may be a different experience than someone else may have had as a child. I may have a more mature perspective or a different way to interpret certain portions. I've never read it before, and I'm not too terribly knowledgeable on the Holocaust. I know about annexing and the genocide and the Hitler and I've read fictional stories on the matter, boy in striped PJs and Devils Arithmetic and others, but as a non-fiction story I'm curious to see how it is.
