Title: Nice introduction to ciphers and codes & interesting, too.
Review: "A person who is interested in this kind of job [cryptology] should study mathematics and computer science. It's never too early to start preparing for your future!" (p.27)Very interesting look at the history and current state of cryptolgy. Includes lots of interesting facts and brief biographies of famous cryptologists and the people they served. Includes the Navajo Code Talkers, the Enigma, and quilt messages. The end of the book as activities like making invisible ink and messages to decifer. Extensive glosssary and index and a six item bibliography. Karen Woodworth-Roman, Children's Science Book Review
