This book offers a great introduction to codes and ciphers！ It is easy to follow and the activities are fun to do。 I loved all the history tidbits throughout the book！

Out of 5 stars， with 3 being an average， I give this one 4。5 stars。 It is a helpful and easy to understand explanation of codes and ciphers， with some cipher and code-breaking history mixed in。 There are pages to practice both enciphering and deciphering messages。

Paged through this and worth revisiting in the future。 At age five， Morse code was the most accessible of the topics。

WOW， THIS BOOK WAS VERY COOL AND FUN！ I learned a lot about code writing and all the different secret codes that have meanings！ I didn't get to memorize a lot of them and some of them were hard to understand。 That is why I didn't but one more star BUT。。。 This book deserves more likes！！！ So underrated！！！！！！ WOW， THIS BOOK WAS VERY COOL AND FUN！ I learned a lot about code writing and all the different secret codes that have meanings！ I didn't get to memorize a lot of them and some of them were hard to understand。 That is why I didn't but one more star BUT。。。 This book deserves more likes！！！ So underrated！！！！！！ 。。。more

I would have loved this as a kid。 It is even better than the code book I had when I was a little girl。

Such a fun book， with approachable ciphers and codes for middle schoolers。 Used it for an escape room activity at our middle school。 Highly recommend！

I really liked this book。 I'm currently playing a murder mystery game and it involves the use of codes and ciphers to solve some of the clues。 It helped a lot。 found it very interesting。 I really liked this book。 I'm currently playing a murder mystery game and it involves the use of codes and ciphers to solve some of the clues。 It helped a lot。 found it very interesting。 。。。more

Written for kids， and very easy to understand different codes and ciphers。 A really fun book to read with my kids， and fun to have moments to practice making and breaking codes。

An easy and fun introduction to codes and ciphers。 Plus， I learned the difference between a code and a cipher， so I'd call that a definite win。 An easy and fun introduction to codes and ciphers。 Plus， I learned the difference between a code and a cipher， so I'd call that a definite win。 。。。more

It contained a good amount of information but it was quite unclear at times。 It did contain good examples and explanations so I hope that kids would walk away from reading it bother entertained， intrigued and curious about human ingenuity and strategical thinking thoughout history。

I read this to get ideas for a program I am doing at the library。 It was a wonderful guide to not only the history of codes， but a wide variety of different types of codes and ciphers。 Many of them would make excellent additions to my program。 Some of the ones I enjoyed learning about were the Rosicrucian and the Playing Card codes。 As a book to read itself it was fascinating， I learned a lot about cryptography。

Not interesting enough to read cover to cover， but fun to skim through the different ciphers。 Would probably keep a kid busy for a while， or even an adult with an interest in ciphers。

Sure， it's a book for little kids。 It has 14-point font， cartoon illustrations， and easy language， but it also has little bits of history （the interesting kind） and a lot of ciphers to practice with friends。 Which is exactly my plan。 （I'm coming for you， Jean！） Sure， it's a book for little kids。 It has 14-point font， cartoon illustrations， and easy language， but it also has little bits of history （the interesting kind） and a lot of ciphers to practice with friends。 Which is exactly my plan。 （I'm coming for you， Jean！） 。。。more

Top Secret is a fascinating book about secret codes for kids。 The book is divided into three sections。 The first focuses on making many different kinds of codes and ciphers。 The section section then focuses on the breaking of those codes。 The third section focuses on different ways to conceal codes。 Paul Janeczko writes in a way that very inviting to children。 It's obvious that he shares a great love for codes and cipher and that enthusiasm can be infectious。 Every section that introduces a new Top Secret is a fascinating book about secret codes for kids。 The book is divided into three sections。 The first focuses on making many different kinds of codes and ciphers。 The section section then focuses on the breaking of those codes。 The third section focuses on different ways to conceal codes。 Paul Janeczko writes in a way that very inviting to children。 It's obvious that he shares a great love for codes and cipher and that enthusiasm can be infectious。 Every section that introduces a new type of code and cipher includes clear directions and examples for children to try on their own。 The solutions can be found in the back。 The book is scattered with various illustrations bu Jeanna LaReau that feature a male and female spy making and breaking codes。 They are attractive and do a good job of emphasizing the feeling of teamwork that Janeczko is trying to emphasize in this book。 There is also a history element to this book as the author gives background information on some of the codes， as well as highlights famous spies from history。 The historical aspect， although not the focus of the book， does a good job on grounding the activities in real life。 Top Secret is a well put together book and an appropriate choice for clever children that want to learn more about codes， ciphers， and secret writing。Note: This review was written for a class 。。。more
