i have to give this book a 5 because it was soooo good. I don't rlly read a lot, but I had to read this for a project in school and could not put it down! I cried, I smiled, I gasped, just like I'm sure everyone else who read it did. this was an amazing book. I am really sorry for Dave and I'm glad he followed his dreams and joined the Air Force!! For those who liked this book you should read the sequel!
