Query: Opening eyes

This is an awesome book. I just finished learning about the Holocaust in a history class, but this put everything into perspective. I usually like books that I can relate to more or that have to do w/ teens like myself, but this is a book that I could never put down, I read it from cover to cover in 2 days! Because of this book, I am looking forward to reading other books that are related to history, it really opened my eyes to a new genre of literature.
