At the surface, this book walks the reader through the difference between a code and a cipher. We are given, first, a very simple example of each and then are introduced to increasingly complex types of codes and ciphers with extra emphasis on the latter. That will be interesting to most middle grade readers all on it's own. Then Schwartz introduces cipher wheels and the Enigma machine. It's an important turning point. Enigma taught the world a lot about cryptography and code breaking. And the study of Enigma leads directly into modern encryption. While this is a basic introduction to the concept, it's clear and accessible. I'd recommend it not only to kids with and interest in codes but also to adults who want to start understanding encryption.
