Book excerpt: “Suspenseful…emotionally compelling. I found myself eagerly following in a way I hadn’t remembered for a long time, impatient for the next twist and turn of the story."—NPR An Afghan American woman returns to Kabul to learn the truth about her family and the tragedy that destroyed their lives in this brilliant and compelling novel from the bestselling author of The Pearl That Broke Its Shell, The House Without Windows, and When the Moon Is Low. Kabul, 1978: The daughter of a prominent family, Sitara Zamani lives a privileged life in Afghanistan’s thriving cosmopolitan capital. The 1970s are a time of remarkable promise under the leadership of people like Sardar Daoud, Afghanistan’s progressive president, and Sitara’s beloved father, his right-hand man. But the ten-year-old Sitara’s world is shattered when communists stage a coup, assassinating the president and Sitara’s entire family. Only she survives. Smuggled out of the palace by a guard named Shair, Sitara finds her way to the home of a female American diplomat, who adopts her and raises her in America. In her new country, Sitara takes on a new name—Aryana Shepherd—and throws herself into her studies, eventually becoming a renowned surgeon. A survivor, Aryana has refused to look back, choosing instead to bury the trauma and devastating loss she endured. New York, 2008: Thirty years after that fatal night in Kabul, Aryana’s world is rocked again when an elderly patient appears in her examination room—a man she never expected to see again. It is Shair, the soldier who saved her, yet may have murdered her entire family. Seeing him awakens Aryana’s fury and desire for answers—and, perhaps, revenge. Realizing that she cannot go on without finding the truth, Aryana embarks on a quest that takes her back to Kabul—a battleground between the corrupt government and the fundamentalist Taliban—and through shadowy memories of the world she loved and lost. Bold, illuminating, heartbreaking, yet hopeful, Sparks Like Stars is a story of home—of America and Afghanistan, tragedy and survival, reinvention and remembrance, told in Nadia Hashimi’s singular voice.

Download or read book The Only Plane in the Sky written by Garrett M. Graff and published by Avid Reader Press / Simon & Schuster. This book was released on 2019-09-10 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: NEW YORK TIMES BESTSELLER “This is history at its most immediate and moving…A marvelous and memorable book.” —Jon Meacham “Remarkable…A priceless civic gift…On page after page, a reader will encounter words that startle, or make him angry, or heartbroken.” —The Wall Street Journal “Visceral...I repeatedly cried…This book captures the emotions and unspooling horror of the day.” —NPR “Had me turning each page with my heart in my throat…There’s been a lot written about 9/11, but nothing like this. I urge you to read it.” —Katie Couric The first comprehensive oral history of September 11, 2001—a panoramic narrative woven from the voices of Americans on the front lines of an unprecedented national trauma. Over the past eighteen years, monumental literature has been published about 9/11, from Lawrence Wright’s The Looming Tower, which traced the rise of al-Qaeda, to The 9/11 Commission Report, the government’s definitive factual retrospective of the attacks. But one perspective has been missing up to this point—a 360-degree account of the day told through the voices of the people who experienced it. Now, in The Only Plane in the Sky, award-winning journalist and bestselling historian Garrett Graff tells the story of the day as it was lived—in the words of those who lived it. Drawing on never-before-published transcripts, recently declassified documents, original interviews, and oral histories from nearly five hundred government officials, first responders, witnesses, survivors, friends, and family members, Graff paints the most vivid and human portrait of the September 11 attacks yet. Beginning in the predawn hours of airports in the Northeast, we meet the ticket agents who unknowingly usher terrorists onto their flights, and the flight attendants inside the hijacked planes. In New York City, first responders confront a scene of unimaginable horror at the Twin Towers. From a secret bunker underneath the White House, officials watch for incoming planes on radar. Aboard the small number of unarmed fighter jets in the air, pilots make a pact to fly into a hijacked airliner if necessary to bring it down. In the skies above Pennsylvania, civilians aboard United Flight 93 make the ultimate sacrifice in their place. Then, as the day moves forward and flights are grounded nationwide, Air Force One circles the country alone, its passengers isolated and afraid. More than simply a collection of eyewitness testimonies, The Only Plane in the Sky is the historic narrative of how ordinary people grappled with extraordinary events in real time: the father and son working in the North Tower, caught on different ends of the impact zone; the firefighter searching for his wife who works at the World Trade Center; the operator of in-flight telephone calls who promises to share a passenger’s last words with his family; the beloved FDNY chaplain who bravely performs last rites for the dying, losing his own life when the Towers collapse; and the generals at the Pentagon who break down and weep when they are barred from rushing into the burning building to try to rescue their colleagues. At once a powerful tribute to the courage of everyday Americans and an essential addition to the literature of 9/11, The Only Plane in the Sky weaves together the unforgettable personal experiences of the men and women who found themselves caught at the center of an unprecedented human drama. The result is a unique, profound, and searing exploration of humanity on a day that changed the course of history, and all of our lives.

Download or read book Sparks of Life written by James E. Strick and published by Harvard University Press. This book was released on 2009-06-01 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: How, asks James E. Strick, could spontaneous generation--the idea that living things can suddenly arise from nonliving materials--come to take root for a time (even a brief one) in so thoroughly unsuitable a field as British natural theology? No less an authority than Aristotle claimed that cases of spontaneous generation were to be observed in nature, and the idea held sway for centuries. Beginning around the time of the Scientific Revolution, however, the doctrine was increasingly challenged; attempts to prove or disprove it led to important breakthroughs in experimental design and laboratory techniques, most notably sterilization methods, that became the cornerstones of modern microbiology and sped the ascendancy of the germ theory of disease. The Victorian debates, Strick shows, were entwined with the public controversy over Darwin's theory of evolution. While other histories of the debates between 1860 and 1880 have focused largely on the experiments of John Tyndall, Henry Charlton Bastian, and others, Sparks of Life emphasizes previously understudied changes in the theories that underlay the debates. Strick argues that the disputes cannot be understood without full knowledge of the factional infighting among Darwinians themselves, as they struggled to create a socially and scientifically viable form of Darwinian science. He shows that even the terms of the debate, such as biogenesis, usually but incorrectly attributed to Huxley, were intensely contested.
