I found the book to be an interesting introduction to codes and ciphers but for the hard core dedicated cryptologist it might be a bit basic. The book begins with history's earliest coding through modern systems and give easy to understand examples of each. There were several that I was not acquainted with and found them to be easy to understand from the sample text. It is as good a book as you might find anywhere for a gift to a friend who has just become aware of the world of cryptography.
