"[S]hines a spotlight on cryptology, both its long history and its place in the modern world. . . . Quality material for a research paper."—School Library Journal

From the Publisher

Gr 4–7—This series shines a spotlight on cryptology, both its long history and its place in the modern world. Young readers will be introduced to influential people in the history of cryptology and their contributions to the field. They will also discover the importance of digital cryptology in the cyber age. The series examines complicated subjects such as blockchain with simplified language, but it might still be too difficult for some younger readers to understand. Throughout the books, the author includes "STEAM spotlights," which draw attention to one of the STEAM subjects within cryptology. For example, the use of art to create Sumerian cuneiforms, technology to encrypt digital data, and math to use frequency analysis. Each book also includes a craft, glossary, resources, and index. VERDICT Quality material for a research paper but only someone really interested in the topic would pick it up otherwise.
