Through forceful storytelling and wry insight, Levitt and co-author Dubner show that economics is, at root, the study of incentives--how people get what they want, or need, especially when other people want or need the same thing. In Freakonomics, they set out to explore the hidden side of...well, everything. The inner workings of a crack gang. The truth about real-estate agents. The myths of campaign finance. Freakonomics establishes this unconventional premise: If morality represents how we would like the world to work, then economics represents how it actually does work.

The Spanish flu of 1918-1920 was one of the greatest human disasters of all time. It infected a third of the people on Earth--from the poorest immigrants of New York City to the king of Spain, Franz Kafka, Mahatma Gandhi and Woodrow Wilson. But despite a death toll of between 50 and 100 million people, it exists in our memory as an afterthought to World War I. In this gripping narrative history, Laura Spinney traces the overlooked pandemic to reveal how the virus travelled across the globe, exposing mankind's vulnerability and putting our ingenuity to the test.

Road Through Time begins with the story of how anatomically modern humans left Africa to populate the world. She then carries us along the Silk Road in Central Asia, and tells of roads built for war in Persia, the Andes, and the Roman Empire. She sails across the seas, and introduces the first railways, all before plunking us down in the middle of a massive, modern freeway. The book closes with a view from the end of the road, literally and figuratively, asking, can we meet the challenges presented by a mode of travel dependent on hydrocarbons, or will we decline, like so many civilizations that have come before us?

Using the human story of the family-run Midwestern chain Heinen's as an anchor, the narrative dives into the mysterious world of supermarkets and the ways in which we produce, consume, and distribute food. Grocery examines how rapidly supermarkets-and our food and culture-have changed since the days of your friendly neighborhood grocer. But rather than waxing nostalgic for the age of mom-and-pop shops, Ruhlman seeks to understand how our food needs have shifted since the mid-twentieth century, and how these needs mirror our cultural ones.

After his humiliating election defeat in 1912, Roosevelt set his sights on the most punishing physical challenge he could find, the first descent of an unmapped, rapids-choked tributary of the Amazon. Along the way, Roosevelt and his men faced an unbelievable series of hardships, losing their canoes and supplies to punishing whitewater rapids, and enduring starvation, attack, disease, drowning, and a murder within their own ranks. Three men died, and Roosevelt was brought to the brink of suicide. The River of Doubt brings alive these extraordinary events in a powerful nonfiction narrative thriller.

As Markel chronicles the Kelloggs' fascinating, Magnificent Ambersons-like ascent into the pantheon of American industrialists, we see the vast changes in American social mores that took shape in diet, health, medicine, philanthropy, and food manufacturing during seven decades--changing the lives of millions and helping to shape our industrial age.

Tracing the origins and ingredients of our atmosphere, Kean reveals how the alchemy of air reshaped our continents, steered human progress, powered revolutions, and continues to influence everything we do. Along the way, we'll swim with radioactive pigs, witness the most important chemical reactions humans have discovered, and join the crowd at the Moulin Rouge for some of the crudest performance art of all time. Lively, witty, and filled with the astounding science of ordinary life, Caesar's Last Breath illuminates the science stories swirling around us every second.

May 1940 was a month like no other, as the German war machine blazed into France while the supposedly impregnable Maginot Line crumbled, and Winston Churchill replaced Neville Chamberlain as prime minister in an astonishing political drama as Britain, isolated and alone, faced a triumphant Nazi Germany. Against this vast historical canvas, Michael Korda relates what happened and why, and also tells his own story, that of a six-year-old boy in a glamorous movie family who would himself be evacuated. 

A work of immersive journalism steeped in a distinctively American social history and sparked by a personal quest, The Unsettlers traces the search for the simple life through the stories of these new pioneers and what inspired each of them to look for -- or create -- a better existence. Captivating and clear-eyed, it dares us to imagine what a sustainable, ethical, authentic future might actually look like.
