In his first book since the bestselling Fermat's Enigma, Simon Singh offers the first sweeping history of encryption, tracing its evolution and revealing the dramatic effects codes have had on wars, nations, and individual lives. From Mary, Queen of Scots, trapped by her own code, to the Navajo Code Talkers who helped the Allies win World War II, to the incredible (and incredibly simple) logisitical breakthrough that made Internet commerce secure, The Code Book tells the story of the most powerful intellectual weapon ever known: secrecy. Throughout the text are clear technical and mathematical explanations, and portraits of the remarkable personalities who wrote and broke the world's most difficult codes. Accessible, compelling, and remarkably far-reaching, this book will forever alter your view of history and what drives it. It will also make you wonder how private that e-mail you just sent really is.
This compelling story of adventure, romance, and intrigue, set in ancient Egypt, was written by the three-time Newbery Honor and Edgar Award winning author Eloise Jarvis McGraw. Mara is a proud and beautiful slave girl who yearns for freedom in ancient Egypt, under the rule of Queen Hatshepsut. Mara is not like other slaves; she can read and write, as well as speak the language of Babylonian. So, to barter for her freedom, she finds herself playing the dangerous role of double spy for two arch enemies—each of whom supports a contender for the throne of Egypt. Against her will, Mara finds herself falling in love with one of her masters, the noble Sheftu, and she starts to believe in his plans of restoring Thutmose III to the throne. But just when Mara is ready to offer Sheftu her help and her heart, her duplicity is discovered, and a battle ensues in which both Mara’s life and the fate of Egypt are at stake. “Dangerous espionage, an unusual love story, and richly drawn background make this a book to capture quick and lasting interest.”—Horn Book “Thoroughly engrossing.”—Kirkus Reviews
A surprising adventure exploring the mysterious origins of Ancient Egypt and its enigmatic monuments, uncovering long-buried truths and a powerful secret that is as dangerous as it is awe-inspiring...
