Reviews

[Duane]

For young readers who are interested in learning about codes and secret spy techniques, then this is a great book for them! Filled with great photographs and illustrations, the book goes through the history of codes/ciphers and how they've advanced through the years. A great bonus is that each type of code is explained in detail and there are exercises for the reader to experiment with. A great book for anyone's collection.
