I read this book for book club a few months back and really enjoyed it. After I picked up I Am the Messenger, also by Zusak, and realized that I loved this book even more. It's a story of second chances and how one one event can change your life forever. It is a funny and thoughtful adventure ripe with unusual characters.
So if you are going to read The Book Thief (and even if you are not) I recommend that you pick up I Am the Messenger as well. Let me know what you think of it (or both books) in the comments section.
