Hands-on history for budding spies, hackers, or anyone with a secret message to send.
Though she starts off with a face-plant—a vague claim, with a disappointingly stereotypical illustration, that “the ancient Chinese” had couriers swallow secret messages written on silk—Schwartz goes on to offer a broad and lucid survey of cryptographic strategies. These range from steganography and substitution ciphers to second factor authentication and other recent trends in cybersecurity. She also provides plenty of variously coded examples for readers to decipher as practice, capped by a final challenge to go back and find the clues to a secret message that have been distributed throughout. Her detailed description of how the German Enigma machine worked (and was hacked by the Bletchley Park group in World War II) is indeed “fascinating,” as are the close analyses of still-unsolved messages such as the modern Kryptos inscription outside CIA headquarters. Somewhat less fascinating are the closing chapters, in which she does explain how prime numbers figure in securing internet communications but neglects to mention the possibilities of quantum cryptography and leaves a debatable impression that cyber defenses have been generally successful in staying ahead of “black hat” hackers. Williams adds a diverse group of spot-art figures to go with the array of tables, diagrams, and occasional photos.

BOOK REVIEW
If Freedman wrote the history textbooks, we would have many more historians. Beginning with an engrossing description of the Boston Tea Party in 1773, he brings the reader the lives of the American colonists and the events leading up to the break with England. The narrative approach to history reads like a good story, yet Freedman tucks in the data that give depth to it. The inclusion of all the people who lived during those times and the roles they played, whether small or large are acknowledged with dignity. The story moves backwards from the Boston Tea Party to the beginning of the European settlement of what they called the New World, and then proceeds chronologically to the signing of the Declaration. “Your Rights and Mine” traces the influence of the document from its inception to the present ending with Martin Luther King and the Civil Rights movement of the 1960s. The full text of the Declaration and a reproduction of the original are included. A chronology of events and an index are helpful to the young researcher. Another interesting feature is “Visiting the Declaration of Independence.” It contains a short review of what happened to the document in the years after it was written, a useful Web site, and a description of how it is displayed and protected today at the National Archives building in Washington, D.C. Illustrations from the period add interest and detail. An excellent addition to the American history collection and an engrossing read. (Nonfiction. 9-13)

Logically pointing out that the American cowboy archetype didn’t spring up from nowhere, Sandler, author of Cowboys (1994) and other volumes in the superficial, if luxuriously illustrated, “Library of Congress Book” series, looks back over 400 years of cattle tending in North America. His coverage ranges from the livestock carried on Columbus’s second voyage to today’s herding-by-helicopter operations. Here, too, the generous array of dramatic early prints, paintings, and photos are more likely to capture readers’ imaginations than the generality-ridden text. But among his vague comments about the characters, values, and culture passed by Mexican vaqueros to later arrivals from the Eastern US, Sadler intersperses nods to the gauchos, llaneros, and other South American “cowmen,” plus the paniolos of Hawaii, and the renowned African-American cowboys. He also decries the role film and popular literature have played in suppressing the vaqueros’ place in the history of the American West. He tackles an uncommon topic, and will broaden the historical perspective of many young cowboy fans, but his glance at modern vaqueros seems to stop at this country’s borders. Young readers will get a far more detailed, vivid picture of vaquero life and work from the cowboy classics in his annotated bibliography. (Notes, glossary, index) (Nonfiction. 10-12)
