The award-winning national bestseller about the American women who secretly served as codebreakers during World War II--a "prodigiously researched and engrossing" (New York Times) book that "shines a light on a hidden chapter of American history" (Denver Post). Recruited by the U.S. Army and Navy from small towns and elite colleges, more than ten thousand women served as codebreakers during World War II. While their brothers and boyfriends took up arms, these women moved to Washington and learned the meticulous work of code-breaking. Their efforts shortened the war, saved countless lives, and gave them access to careers previously denied to them. A strict vow of secrecy nearly erased their efforts from history; now, through dazzling research and interviews with surviving code girls, bestselling author Liza Mundy brings to life this riveting and vital story of American courage, service, and scientific accomplishment.

The magnificent, unrivaled history of codes and ciphers -- how they're made, how they're broken, and the many and fascinating roles they've played since the dawn of civilization in war, business, diplomacy, and espionage -- updated with a new chapter on computer cryptography and the Ultra secret. Man has created codes to keep secrets and has broken codes to learn those secrets since the time of the Pharaohs. For 4,000 years, fierce battles have been waged between codemakers and codebreakers, and the story of these battles is civilization's secret history, the hidden account of how wars were won and lost, diplomatic intrigues foiled, business secrets stolen, governments ruined, computers hacked. From the XYZ Affair to the Dreyfus Affair, from the Gallic War to the Persian Gulf, from Druidic runes and the kaballah to outer space, from the Zimmermann telegram to Enigma to the Manhattan Project, codebreaking has shaped the course of human events to an extent beyond any easy reckoning. Once a government monopoly, cryptology today touches everybody. It secures the Internet, keeps e-mail private, maintains the integrity of cash machine transactions, and scrambles TV signals on unpaid-for channels. David Kahn's The Codebreakers takes the measure of what codes and codebreaking have meant in human history in a single comprehensive account, astonishing in its scope and enthralling in its execution. Hailed upon first publication as a book likely to become the definitive work of its kind, The Codebreakers has more than lived up to that prediction: it remains unsurpassed. With a brilliant new chapter that makes use of previously classified documents to bring the book thoroughly up to date, and to explore the myriad ways computer codes and their hackers are changing all of our lives, The Codebreakers is the skeleton key to a thousand thrilling true stories of intrigue, mystery, and adventure. It is a masterpiece of the historian's art.

Bryn Reyes is a real life sleeping beauty. Afflicted with Klein-Levin Syndrome, she suffers episodes of prolonged sleep that steal weeks, and sometimes even months, from her life. But unlike most KLS patients, she doesn’t spend each episode in a catatonic state or wake up with no recollection of the time she’s missed. Instead, Bryn spends half her life in an alternate reality made up of her memories. For Bryn, the past is a place, until one day a boy she’s never met before washes up on the illusory beach of her dreams with no memory of who he is. But the appearance of this strange boy isn’t the only thing that’s changed. Bryn’s symptoms are worsening, her body weakening as she’s plagued by hallucinations even while awake. Her only hope of finding a cure is to undergo experimental treatment created by a German specialist. But when Dr. Banz reveals that he knows more about her strange symptoms than he originally let on, Bryn learns that the boy in her head might actually be the key to understanding what’s happening to her, and worse, that if she doesn’t find out his identity before it’s too late, they both may not survive.

In Adam Burch’s thrilling series debut, a young man must choose between violence and peace in a distant world divided between those who thrive in endless sunlight and those who survive in eternal darkness. The isolated planet of Tao is a house divided: the peaceful Daysiders live in harmony while the pale Nightsiders pursue power and racial purity through the violent ritual of the Combat. Edmon Leontes, the gentle son of a ruthless warrior noble and a proud Daysider, embodies Tao’s split nature. The product of diametrically opposed races, Edmon hopes to live a quiet life pursuing the music of his mother’s people, but his Nightsider father cruelly forces him to continue in his bloody footsteps to ensure his legacy. Edmon’s defiance will cost him everything…and spark a revolution that will shake the foundations of Tao. His choice—to embrace the light or surrender to the darkness—will shape his own fate and that of his divided world.

As an instructor at the University of Tulsa, Christopher Swenson could find no relevant text for teaching modern cryptanalysis?so he wrote his own. This is the first book that brings the study of cryptanalysis into the 21st century. Swenson provides a foundation in traditional cryptanalysis, examines ciphers based on number theory, explores block ciphers, and teaches the basis of all modern cryptanalysis: linear and differential cryptanalysis. This time-honored weapon of warfare has become a key piece of artillery in the battle for information security.

STATION X tells the true story, as it has never been told before, of the amazing achievements of the codebreakers working at Bletchley Park in the Second World War.In 1939, several hundred people - students, professors, international chess players, junior military officers, actresses and debutantes - reported to a Victorian mansion in Buckinghamshire: Bletchley Park. This was to be 'Station X', the Allies' top-secret centre for deciphering enemy codes. Their task was to break the ingenious Enigma code used for German high-level communications. The settings for the Enigma machine changed continually and each day the German operators had 159 million million million different possibilities. Yet against all the odds this gifted group achieved the impossible, coping with even greater difficulties to break Shark, the U-Boat Enigma, and Fish, the cypher system used by Hitler to talk to his guards.
