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 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.

A visceral drama, When the Sea Came Alive is the most comprehensive account of D-Day that we have yet to see, and an unforgettable, fitting tribute to the men and women of the Greatest Generation.

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.

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.

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.

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.

My Big TOE: Awakening, written by a nuclear physicist in the language of contemporary culture, unifies science and philosophy, physics and metaphysics, mind and matter, purpose and meaning, the normal and the paranormal.

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.
