In this book the author asks whether you have what it takes to be a codebreaker. This is not because he wants to teach you how to do this; rather, to present challenges for the mind. Code breaking is not easy. The author introduces twelve codes he invented. He presents a message written in these codes. He even tells you what the message says. Your task is to discover how the codes work and prove it by decoding a validation message for each of them. What is your reward? Simply the pleasure of having accomplished doing something that is difficult to do. If you email the author at email@example.com telling him this, he'll respond.
