I really like it because it was about spies

I liked this book because it was adventurous.

this is a really cool spy book(it made me want to become a spy) !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

this was pretty good!

Ever wished mystery books let you solve the codes before they tell you? Well, at the end of this book are codes and ansewers. And, before it, is an amazing story about a spy's notebook and a boy living during world war.
