The #1 New York Times bestsellerThe phenomenal true story of the black female mathematicians at NASA whose calculations helped fuel some of America’s greatest achievements in space. Soon to be a major motion picture starring Taraji P. Henson, Octavia Spencer, Janelle Monae, Kirsten Dunst, and Kevin Costner. Before John Glenn orbited the earth, or Neil Armstrong walked on the moon, a group of dedicated female mathematicians known as “human computers” used pencils, slide rules and adding machines to calculate the numbers that would launch rockets, and astronauts, into space. Among these problem-solvers were a group of exceptionally talented African American women, some of the brightest minds of their generation. Originally relegated to teaching math in the South’s segregated public schools, they were called into service during the labor shortages of World War II, when America’s aeronautics industry was in dire need of anyone who had the right stuff. Suddenly, these overlooked math whizzes had a shot at jobs worthy of their skills, and they answered Uncle Sam’s call, moving to Hampton, Virginia and the fascinating, high-energy world of the Langley Memorial Aeronautical Laboratory. Even as Virginia’s Jim Crow laws required them to be segregated from their white counterparts, the women of Langley’s all-black “West Computing” group helped America achieve one of the things it desired most: a decisive victory over the Soviet Union in the Cold War, and complete domination of the heavens. Starting in World War II and moving through to the Cold War, the Civil Rights Movement and the Space Race, Hidden Figures follows the interwoven accounts of Dorothy Vaughan, Mary Jackson, Katherine Johnson and Christine Darden, four African American women who participated in some of NASA’s greatest successes. It chronicles their careers over nearly three decades they faced challenges, forged alliances and used their intellect to change their own lives, and their country’s future.?

The Sunday Times Number 1 Bestseller ‘A fabulous story, superbly told … cannot be bettered’ Max Hastings ‘Some battles change nothing. Waterloo changed almost everything.’ On the 18th June 1815 the armies of France, Britain and Prussia descended upon a quiet valley south of Brussels. In the previous three days the French army had beaten the British at Quatre-Bras and the Prussians at Ligny. The Allies were in retreat. The blood-soaked battle of Waterloo would become a landmark in European history, to be examined over and again, not least because until the evening of the 18th, the French army was close to prevailing on the battlefield. Now, brought to life by the celebrated novelist Bernard Cornwell, this is the chronicle of the four days leading up to the actual battle and a thrilling hour-by-hour account of that fateful day. In his first work of non-fiction, Cornwell combines his storytelling skills with a meticulously researched history to give a riveting account of every dramatic moment, from Napoleon’s escape from Elba to the smoke and gore of the battlefields. Through letters and diaries he also sheds new light on the private thoughts of Napoleon and the Duke of Wellington, as well as the ordinary officers and soldiers. Published to coincide with the bicentenary in 2015, Waterloo is a tense and gripping story of heroism and tragedy – and of the final battle that determined the fate of Europe.
