America was made by the railroads. The opening of the Baltimore & Ohio line—the first American railroad—in the 1830s sparked a national revolution in the way that people lived thanks to the speed and convenience of train travel. Built through heroic effort, the American railroad network was bigger in every sense than Europe's, and facilitated everything from long-distance travel to commuting and transporting goods to waging war. It united far-flung parts of the country, boosted economic development, and was the catalyst for America's rise to world-power status.

In April 1942, the Imperial Japanese Army steamrolled through Burma, capturing the only ground route from India to China. Supplies to this critical zone would now have to come from India by air—meaning across the Himalayas, on the most hazardous air route in the world. SKIES OF THUNDER is a story of an epic human endeavor, in which Allied troops faced the monumental challenge of operating from airfields hacked from the jungle, and took on “the Hump,” the fearsome mountain barrier that defined the air route.

On June 6, 1944, General Dwight Eisenhower addressed the thousands of American troops preparing to invade Normandy, exhorting them to embrace the “Great Crusade” they faced. Then, in a fleeting moment alone, he drafted a resignation letter in case the invasion failed. In The Light of Battle, Michel Paradis, acclaimed author of Last Mission to Tokyo, paints a vivid portrait of Dwight Eisenhower as he learns to navigate the crosscurrents of diplomacy, politics, strategy, family, and fame with the fate of the free world hanging in the balance.

On November 6, 1860, Abraham Lincoln became the fluky victor in a tight race for president. The country was bitterly at odds; Southern extremists were moving ever closer to destroying the Union, with one state after another seceding and Lincoln powerless to stop them. Slavery fueled the conflict, but somehow the passions of North and South came to focus on a lonely federal fortress in Charleston Harbor: Fort Sumter.

Milton Friedman was, alongside John Maynard Keynes, the most influential economist of the twentieth century. His work was instrumental in the turn toward free markets that defined the 1980s, and his full-throated defenses of capitalism and freedom resonated with audiences around the world. It’s no wonder the last decades of the twentieth century have been called “the Age of Friedman”—or that analysts have sought to hold him responsible for both the rising prosperity and the social ills of recent times. Historian Jennifer Burns tells Friedman’s extraordinary story with the nuance it deserves.

The Gulag - a vast array of Soviet concentration camps that held millions of political and criminal prisoners - was a system of repression and punishment that terrorized the entire society, embodying the worst tendencies of Soviet communism. In this magisterial and acclaimed history, Anne Applebaum offers the first fully documented portrait of the Gulag, from its origins in the Russian Revolution, through its expansion under Stalin, to its collapse in the era of glasnost.

German military history is typically viewed as an inexorable march to the rise of Prussia and the two world wars, the road paved by militarism and the result a specifically German way of war. Peter Wilson challenges this narrative. Looking beyond Prussia to German-speaking Europe across the last five centuries, Wilson finds little unique or preordained in German militarism or warfighting. Iron and Blood takes as its starting point the consolidation of the Holy Roman Empire, which created new mechanisms for raising troops but also for resolving disputes diplomatically.

War can settle disputes, topple tyrants, and bend the trajectory of civilization—sometimes to the breaking point. From Troy to Hiroshima, moments when war has ended in utter annihilation have reverberated through the centuries, signaling the end of political systems, cultures, and epochs. Though much has changed over the millennia, human nature remains the same. In The End of Everything, military historian Victor Davis Hanson narrates a series of sieges and sackings that span the age of antiquity to the conquest of the New World to show how societies descend into barbarism and obliteration.

At the beginning of November 1942, it looked as if the Axis powers could still win the Second World War; at the end of that month, it was just a matter of time before they would lose. In between was El Alamein, Guadalcanal, the French North Africa landings, the Japanese retreat in New Guinea, and the Soviet encirclement of the German 6th Army at Stalingrad. It may have been the most important month of the twentieth century. In this hugely innovative and riveting historical marvel, Peter Englund has reduced an epoch-making event to its basic component: the individual experience.

On the stormy night of August 29, 1776, the Continental Army faced annihilation after losing the Battle of Brooklyn. The British had trapped George Washington’s army against the East River, and the fate of the Revolution rested upon the shoulders of the soldier-mariners from Marblehead, Massachusetts. Serving side-by-side in one of the country’s first diverse units, they pulled off an “American Dunkirk” and saved the army by navigating the treacherous waters of the river to Manhattan.

Richard Dawkins' brilliant reformulation of the theory of natural selection has the rare distinction of having provoked as much excitement and interest outside the scientific community as within it. His theories have helped change the whole nature of the study of social biology, and have forced thousands to rethink their beliefs about life.

Astrophysicist Neil deGrasse Tyson has attracted one of the world’s largest online followings with his fascinating, widely accessible insights into science and our universe.

In The Butchering Art, the historian Lindsey Fitzharris reveals the shocking world of 19th-century surgery on the eve of profound transformation. She conjures up early operating theaters - no place for the squeamish - and surgeons, working before anesthesia, who were lauded for their speed and brute strength. They were baffled by the persistent infections that kept mortality rates stubbornly high. A young, melancholy Quaker surgeon named Joseph Lister would solve the deadly riddle and change the course of history.
