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.

In February 1944, in one of the most astonishing battles of World War II, a ragtag collection of British clerks, drivers, doctors, muleteers, and other base troops, stiffened by a few dogged Yorkshiremen and a handful of tank crews, managed to defeat a much larger and sophisticated contingent of some of the finest infantry in the Japanese army on their march toward India.

In the dark days after the devastating Pearl Harbor attacks during the spring of 1942, the United States was determined to show the world that the Axis was not invincible. Their bold plan? Bomb Tokyo. On April 18, 1942, sixteen B-25s, known as the Doolittle Raiders, hit targets across Japan before escaping to China. The eighth plane, however, did not follow the other raiders. Instead, Plane 8's pilots, Captain Edward "Ski" York and Lieutenant Bob Emmens, never attacked Tokyo, but headed across Japan to the Soviet Union, supposedly due to low fuel.

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.

Red Dead Redemption and Red Dead Redemption II, set in 1911 and 1899, are the most-played American history video games since The Oregon Trail. Beloved by millions, they’ve been widely acclaimed for their realism and attention to detail. But how do they fare as re-creations of history? In this engaging audiobook, award-winning American history professor Tore Olsson takes up that question and more.

Over thousands of years, the Mississippi watershed was home to millions of Indigenous people who regarded "the great river" with awe and respect, adorning its banks with astonishing spiritual earthworks. But European settlers and American pioneers had a different vision: the river was a foe to conquer. In this landmark work of natural history, Boyce Upholt tells the epic story of human attempts to own and contain the Mississippi River, from Thomas Jefferson's expansionist land hunger through today's era of environmental concern

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.
