This book has everything you could ever want to know about spies and secret codes. You can learn the history of spies and secret plans, and how to crack ciphers and codes. There are sections about famous spies, gadgets, secret fortresses, and classified information!
I love the design of this book! There are colorful photographs on every page, and the information is divided into boxes that make it easy to read all those factoids and snippets of history.
I especially liked the section about myths vs. facts, that debunks a lot of common misconceptions about secret agents and what they do. And there are cute things like how to come up with your own secret handshake to share with your friends, and how to create your own disguise.
There is an entire spread all about the secret passages and trapdoors under the Colosseum. And there are a few pages about secret societies like the Masons and the Illuminati. Ninja fans will like hearing about the secret identities of ninjas, and how people would set up traps and alarms to warn them if a ninja was coming for them. So many cool things in this book!
