Winner of the Hugo and Nebula Awards
In order to develop a secure defense against a hostile alien race's next attack, government agencies breed child geniuses and train them as soldiers. A brilliant young boy, Andrew "Ender" Wiggin lives with his kind but distant parents, his sadistic brother Peter, and the person he loves more than anyone else, his sister Valentine. Peter and Valentine were candidates for the soldier-training program but didn't make the cut--young Ender is the Wiggin drafted to the orbiting Battle School for rigorous military training.
Ender's skills make him a leader in school and respected in the Battle Room, where children play at mock battles in zero gravity. Yet growing up in an artificial community of young soldiers Ender suffers greatly from isolation, rivalry from his peers, pressure from the adult teachers, and an unsettling fear of the alien invaders. His psychological battles include loneliness, fear that he is becoming like the cruel brother he remembers, and fanning the flames of devotion to his beloved sister.
Is Ender the general Earth needs? But Ender is not the only result of the genetic experiments. The war with the Buggers has been raging for a hundred years, and the quest for the perfect general has been underway for almost as long. Ender's two older siblings are every bit as unusual as he is, but in very different ways. Between the three of them lie the abilities to remake a world. If, that is, the world survives. "Ender's Game" is the winner of the 1985 Nebula Award for Best Novel and the 1986 Hugo Award for Best Novel.

Who makes most money from the demand for cappuccinos early in the morning at Waterloo Station? Why is it impossible to get a foot on the property ladder? How does the Mafia make money from laundries when street gangs pushing drugs don't? Who really benefits from immigration? How can China, in just fifty years, go from the world's worst famine to one of the greatest economic revolutions of all time, lifting a million people out of poverty a month? Looking at familiar situations in unfamiliar ways, THE UNDERCOVER ECONOMIST is a fresh explanation of the fundamental principles of the modern economy, illuminated by examples from the streets of London to the booming skyscrapers of Shanghai to the sleepy canals of Bruges. Leaving behind textbook jargon and equations, Tim Harford will reveal the games of signals and negotiations, contests of strength and battles of wit that drive not only the economy at large but the everyday choices we make.

The Professor and the Madman, masterfully researched and eloquently written, is an extraordinary tale of madness, genius, and the incredible obsessions of two remarkable men that led to the making of the Oxford English Dictionary--and literary history. The compilation of the OED, begun in 1857, was one of the most ambitious projects ever undertaken. As definitions were collected, the overseeing committee, led by Professor James Murray, discovered that one man, Dr. W C. Minor, had submitted more than ten thousand. When the committee insisted on honoring him, a shocking truth came to light: Dr. Minor, an American Civil War veteran, was also an inmate at an asylum for the criminally insane.</P>
