Gr 4–8-Schwartz provides a comprehensive and intriguing overview of cryptography, encryption, hacking, and cybersecurity. Beginning with simply coded messages and ciphers, the book follows the logical development of increasingly sophisticated codes throughout historical and contemporary use. Readers are given the opportunity to learn and practice real codes, as well as ways to explore how ciphers and encryption techniques are currently used by the military, secret service, businesses, and even sports teams. Math connections are included as the book demonstrates how computerized encryption utilizes prime numbers of mind-boggling size. Schwartz also explains common cybersecurity techniques such as second-factor authentication and biometrics. Illustrations and photographs clarify the concepts presented. The book concludes with a code-breaking challenge which directs readers to clues scattered throughout the chapters (not seen). This book will prove fascinating to young readers interested in history, technology, math, mysteries, and espionage. Its coverage of codes from the simple to the complex makes it accessible to upper elementary students while still being challenging and thought-provoking for middle school readers. The inclusion of stories about famous codes yet to be deciphered is especially engaging. Of particular value is the discussion about the ethics of information privacy. VERDICT Covers all the bases of an interesting and timely subject; a worthy addition to any collection, particularly where STEM topics are popular.-Kelly Jahng, South Park Elementary School, IL
