How I Became a Spy is a great WWII book filled with adventure and secrets, stopping you at each chapter to solve a riddle. A great book that keeps you on your toes, making you want to skip through the book to know what happens next. Overall a incredible book.

It was awesome and amazing! I really liked it because it was about spies and I really like spies!

So much investagition and mysteryes.

This is a good book.

This is a different kind of mystery story - it's more about how you get to the end than who did it. There are real codes to break along the way, you learn to ask who can be trusted, and a small dog named LR who can save people from bombed out buildings if things get suss. It is cool to read about kids helping win a war and also sad to think about kids having to live through war.
