Awesome It's a great book. Can't wait to use its information in my new psychological thriller for young adults. Recommend it highly to anyone who's interested increating codes or a new secret language.
My son loves this book! We got a number of code books from the library for my 10-year-old son; this one was so well-done that he wanted to buy his own copy. He has been studying this book and using it to develop his own code system. Not too old for a 6-year-old Although this book seems to be recommended for middle schoolers, I bought it for my just-turned 6-year-old son as a birthday gift. We had initially checked it out from our library and he absolutely loved it. Expect to find page upon page of engaging codes and ciphers. Parents are forewarned! Arm yourself with the patience to solve the numerous scribbled codes your kids are going to bring you. Fabulous book. I'm so glad we got our own copy. Another book I'd recommend is Martin Gardner's Codes, Ciphers and Secret Writing.Codes and Ciphers I have of number of books like this. I know that it was more for kids, but I thought it was a fun read and it did have some interesting thoughts I did not find in other books. Overall, I like it very much.It's No Secret, This Book is Great Last summer my son decided he wanted to have spy club, so we looked through every book we could searching for information on how to be a spy. This book had the most thorough treatment of codes, ciphers and the like. It had plenty of activities that I felt like I could set up for the kids and that they could work on their own. This summer we bought the book because we want to reference it so much. Even Mom and Dad like this book.
