Brilliant and engagingly written, Why Nations Fail answers the question that has stumped the experts for centuries: Why are some nations rich and others poor, divided by wealth and poverty, health and sickness, food and famine? Is it culture, the weather, geography? Perhaps ignorance of what the right policies are? Simply, no. None of these factors is either definitive or destiny. Otherwise, how to explain why Botswana has become one of the fastest growing countries in the world, while other African nations, such as Zimbabwe, the Congo, and Sierra Leone, are mired in poverty and violence? Daron Acemoglu and James Robinson conclusively show that it is man-made political and economic institutions that underlie economic success (or lack of it). Korea, to take just one of their fascinating examples, is a remarkably homogeneous nation, yet the people of North Korea are among the poorest on earth while their brothers and sisters in South Korea are among the richest. The south forged a society that created incentives, rewarded innovation, and allowed everyone to participate in economic opportunities. The economic success thus spurred was sustained because the government became accountable and responsive to citizens and the great mass of people. Sadly, the people of the north have endured decades of famine, political repression, and very different economic institutions—with no end in sight. The differences between the Koreas is due to the politics that created these completely different institutional trajectories. Based on fifteen years of original research Acemoglu and Robinson marshall extraordinary historical evidence from the Roman Empire, the Mayan city-states, medieval Venice, the Soviet Union, Latin America, England, Europe, the United States, and Africa to build a new theory of political economy with great relevance for the big questions of today, including: - China has built an authoritarian growth machine. Will it continue to grow at such high speed and overwhelm the West? - Are America’s best days behind it? Are we moving from a virtuous circle in which efforts by elites to aggrandize power are resisted to a vicious one that enriches and empowers a small minority? - What is the most effective way to help move billions of people from the rut of poverty to prosperity? More philanthropy from the wealthy nations of the West? Or learning the hard-won lessons of Acemoglu and Robinson’s breakthrough ideas on the interplay between inclusive political and economic institutions? Why Nations Fail will change the way you look at—and understand—the world.

The brilliance of the novel [is] that it distracts you with these weirdo characters and mesmerizing and funny sentences and then hits you in a way you didn’t see coming. You’re laughing so hard you don’t even realize that you’ve suddenly caught fire.” —Taffy Brodesser-Akner, author of Fleishman is in Trouble, New York Times Book Review From the New York Times bestselling author of The Family Fang, a moving and uproarious novel about a woman who finds meaning in her life when she begins caring for two children with a remarkable ability. Lillian and Madison were unlikely roommates and yet inseparable friends at their elite boarding school. But then Lillian had to leave the school unexpectedly in the wake of a scandal and they’ve barely spoken since. Until now, when Lillian gets a letter from Madison pleading for her help. Madison’s twin stepkids are moving in with her family and she wants Lillian to be their caretaker. However, there’s a catch: the twins spontaneously combust when they get agitated, flames igniting from their skin in a startling but beautiful way. Lillian is convinced Madison is pulling her leg, but it’s the truth. Thinking of her dead-end life at home, the life that has consistently disappointed her, Lillian figures she has nothing to lose. Over the course of one humid, demanding summer, Lillian and the twins learn to trust each other—and stay cool—while also staying out of the way of Madison’s buttoned-up politician husband. Surprised by her own ingenuity yet unused to the intense feelings of protectiveness she feels for them, Lillian ultimately begins to accept that she needs these strange children as much as they need her—urgently and fiercely. Couldn’t this be the start of the amazing life she’d always hoped for? With white-hot wit and a big, tender heart, Kevin Wilson has written his best book yet—a most unusual story of parental love.

New York Times bestselling author Steve Sheinkin presents a follow up to his award-winning book Bomb: The Race to Build--and Steal--the World's Most Dangerous Weapon, taking readers on a terrifying journey into the Cold War and our mutual assured destruction. As World War II comes to a close, the United States and the Soviet Union emerge as the two greatest world powers on extreme opposites of the political spectrum. After the United States showed its hand with the atomic bomb in Hiroshima, the Soviets refuse to be left behind. With communism sweeping the globe, the two nations begin a neck-and-neck competition to build even more destructive bombs and conquer the Space Race. In their battle for dominance, spy planes fly above, armed submarines swim deep below, and undercover agents meet in the dead of night. The Cold War game grows more precarious as weapons are pointed towards each other, with fingers literally on the trigger. The decades-long showdown culminates in the Cuban Missile Crisis, the world's close call with the third—and final—world war.

The Golden Age of Aviation is brought to life in this story of the giant Zeppelin airships that once roamed the sky—a story that ended with the fiery destruction of the Hindenburg. “Genius . . . a definitive tale of an incredible time when mere mortals learned to fly.”—Keith O’Brien, The New York Times At the dawn of the twentieth century, when human flight was still considered an impossibility, Germany’s Count Ferdinand von Zeppelin vied with the Wright Brothers to build the world’s first successful flying machine. As the Wrights labored to invent the airplane, Zeppelin fathered the remarkable airship, sparking a bitter rivalry between the two types of aircraft and their innovators that would last for decades, in the quest to control one of humanity’s most inspiring achievements. And it was the airship—not the airplane—that led the way. In the glittery 1920s, the count’s brilliant protégé, Hugo Eckener, achieved undreamed-of feats of daring and skill, including the extraordinary Round-the-World voyage of the Graf Zeppelin. At a time when America’s airplanes—rickety deathtraps held together by glue, screws, and luck—could barely make it from New York to Washington, D.C., Eckener’s airships serenely traversed oceans without a single crash, fatality, or injury. What Charles Lindbergh almost died doing—crossing the Atlantic in 1927—Eckener had effortlessly accomplished three years before the Spirit of St. Louis even took off. Even as the Nazis sought to exploit Zeppelins for their own nefarious purposes, Eckener built his masterwork, the behemoth Hindenburg—a marvel of design and engineering. Determined to forge an airline empire under the new flagship, Eckener met his match in Juan Trippe, the ruthlessly ambitious king of Pan American Airways, who believed his fleet of next-generation planes would vanquish Eckener’s coming airship armada. It was a fight only one man—and one technology—could win. Countering each other’s moves on the global chessboard, each seeking to wrest the advantage from his rival, the struggle for mastery of the air was a clash not only of technologies but of business, diplomacy, politics, personalities, and the two men’s vastly different dreams of the future. Empires of the Sky is the sweeping, untold tale of the duel that transfixed the world and helped create our modern age.
