Over the summer I read this book;
Night by Elie Wiesel.(He also has two more books in this series that I didn't know about so I will have to get them and read them as well, Dawn and Day.)
There are a lot of things that has happened in the worlds past that unexplainable, and why would any one put another human being in those conditions. It just tares my heart out to see this and know that this is apart of our past.
