"Codes can carry big secrets! Throughout history, lots of good guys and lots of bad guys have used codes to keep their messages under wraps. This fun and flippable nonfiction features stories of hidden treasures, war-time maneuverings, and contemporary hacking as well as explaining the mechanics behind the codes in accessible and kid friendly forms. Sidebars call out activities that invite the reader to try their own hand at cracking and crafting their own secret messages. This is the launch of an exciting new series that invites readers into a STEM topic through compelling historical anecdotes, scientific backup, and DIY projects."

"A broad and lucid survey of cryptographic strategies. These range fromsteganography and substitution ciphers to second factor authenticationand other recent trends in cybersecurity. She also provides plenty ofvariously coded examples for readers to decipher as practice, capped by a final challenge to go back and find the clues to a secret message thathave been distributed throughout. Her detailed description of how theGerman Enigma machine worked (and was hacked by the Bletchley Park group in World War II) is indeed "fascinating," as are the close analyses ofstill-unsolved messages such as the modern Kryptos inscription outside CIA headquarters." - Kirkus Reviews
