I like how it teaches you about different types I codes and that is really cool. I've always found the idea of being a spy interesting and this book really shows you how a boy became a spy in WWII. It is a really awesome book with twists and turns. I recommend this to everyone especially people who like solving mysteries!🔍

We really enjoyed this book. It was a fun one for both the adults and kids. Decoding the ciphers was really fun!

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!
