DOWNLOAD EBOOKKathe Koja's classic, award-winning horror novel is finally available as an ebook. Nicholas, a would-be poet, and Nakota, his feral lover, discover a strange hole in the storage room floor down the hall - "Black. Pure black and the sense of pulsation, especially when you look at it too closely, the sense of something not living but alive." It begins with curiosity, a joke - the Funhole down the hall. But then the experiments begin. "Wouldn't it be wild to go down there?" says Nakota. Nicholas says "We're not." But they're not in control, not from the first moment, as those experiments lead to obsession, violence, and a very final transformation for everyone who gets too close to the Funhole. THE CIPHER was the winner of the 1991 Bram Stoker Award, and was recently named one of io9.com's Top 10 Debut Science Fiction Novels That Took the World By Storm. Long out-of-print and much sought-after, it is finally available as an ebook, with a new foreword by the author. "An ethereal rollercoaster ride from start to finish." - The Detroit Free Press "Combines intensely poetic language and lavish grotesqueries." - BoingBoing "Kathe Koja is a poet ... [T]he kind that prefers to read in seedy bars instead of universities, but a poet." - The New York Review of Science Fiction "Her 20-something characters are poverty-gagged 'artists' who exist in that demimonde of shitty jobs, squalid art galleries, and thrift stores; her settings are run-down studios, flat-beer bars, and dingy urban streets [a] long way from Castle Rock, Dunwich, or Stepford, that's for sure." - Too Much Horror Fiction "This powerful first novel is as thought-provoking as it is horrifying." - Publishers Weekly "Unforgettable ... [THE CIPHER] takes you into the lives of the dark dreamers that crawl on the underbelly of art and culture. Seldom has language been so visceral and so right." - Locus "[THE CIPHER] is a book that makes you sit up, pay attention, and jettison your moldy preconceptions about the genre ... Utterly original ... [An} imaginative debut." - Fangoria "Not so much about the vast and wonderful strangeness of the universe as it is about the horrific and glorious potential of the human spirit." - Short Form

DOWNLOAD EBOOKThe explosive narrative of the life, captivity, and trial of Bowe Bergdahl, the soldier who was abducted by the Taliban and whose story has served as a symbol for America's foundering war in Afghanistan ”An unsettling and riveting book filled with the mysteries of human nature.” —Kirkus Private First Class Bowe Bergdahl left his platoon's base in eastern Afghanistan in the early hours of June 30, 2009. Since that day, easy answers to the many questions surrounding his case—why did he leave his post? What kinds of efforts were made to recover him from the Taliban? And why, facing a court martial, did he plead guilty to the serious charges against him?—have proved elusive. Taut in its pacing but sweeping in its scope, American Cipher is the riveting and deeply sourced account of the nearly decade-old Bergdahl quagmire—which, as journalists Matt Farwell and Michael Ames persuasively argue, is as illuminating an episode as we have as we seek the larger truths of how the United States lost its way in Afghanistan. The book tells the parallel stories of a young man's halting coming of age and a nation stalled in an unwinnable war, revealing the fallout that ensued when the two collided: a fumbling recovery effort that suppressed intelligence on Bergdahl's true location and bungled multiple opportunities to bring him back sooner; a homecoming that served to deepen the nation's already-vast political fissure; a trial that cast judgment on not only the defendant, but most everyone involved. The book's beating heart is Bergdahl himself—an idealistic, misguided soldier onto whom a nation projected the political and emotional complications of service. Based on years of exclusive reporting drawing on dozens of sources throughout the military, government, and Bergdahl's family, friends, and fellow soldiers, American Cipher is at once a meticulous investigation of government dysfunction and political posturing, a blistering commentary on America's presence in Afghanistan, and a heartbreaking story of a naïve young man who thought he could fix the world and wound up the tool of forces far beyond his understanding.

DOWNLOAD EBOOKWhen the United States declared war on Germany in April 1917, it was woefully unprepared to wage a modern war. Whereas their European counterparts already had three years of experience in using code and cipher systems in the war, American cryptologists had to help in the building of a military intelligence unit from scratch. This book relates the personal experiences of one such character, providing a uniquely American perspective on the Great War. It is a story of spies, coded letters, plots to blow up ships and munitions plants, secret inks, arms smuggling, treason, and desperate battlefield messages. Yet it all begins with a college English professor and Chaucer scholar named John Mathews Manly. In 1927, John Manly wrote a series of articles on his service in the Code and Cipher Section (MI-8) of the U.S. Army’s Military Intelligence Division (MID) during World War I. Published here for the first time, enhanced with references and annotations for additional context, these articles form the basis of an exciting exploration of American military intelligence and counter-espionage in 1917-1918. Illustrating the thoughts of prisoners of war, draftees, German spies, and ordinary Americans with secrets to hide, the messages deciphered by Manly provide a fascinating insight into the state of mind of a nation at war.

DOWNLOAD EBOOK"A cipher is a scheme for creating coded messages for the secure exchange of information. Throughout history, many different coding schemes have been devised. One of the oldest and simplest mathematical systems was used by Julius Caesar. This is where Mathematical Ciphers begins. Building on that simple system, Young moves on to more complicated schemes, ultimately ending with the RSA cipher, which is used to provide security for the Internet. This book is structured differently from most mathematics texts. It does not begin with a mathematical topic, but rather with a cipher. The mathematics is developed as it is needed; the applications motivate the mathematics. As is typical in mathematics textbooks, most chapters end with exercises. Many of these problems are similar to solved examples and are designed to assist the reader in mastering the basic material. A few of the exercises are one-of-a-kind, intended to challenge the interested reader. Implementing encryption schemes is considerably easier with the use of the computer. For all the ciphers introduced in this book, JavaScript programs are available from the Web. In addition to developing various encryption schemes, this book also introduces the reader to number theory. Here, the study of integers and their properties is placed in the exciting and modern context of cryptology. Mathematical Ciphers can be used as a textbook for an introductory course in mathematics for all majors. The only prerequisite is high school mathematics."--Jacket.
