As 1909 dawned, the greatest jewels of exploration - set at the world's frozen extremes - lay unclaimed: the North and South Poles and the so-called "Third Pole", the pole of altitude, located in unexplored heights of the Himalaya. Before the calendar turned, three expeditions had faced death, mutiny, and the harshest conditions on the planet to plant flags at the furthest edges of the Earth.

Drawing on his decades of field research and up-to-the-minute understanding of the latest science, renowned geologist Andrew H. Knoll delivers a rigorous yet accessible biography of Earth, charting our home planet's epic 4.6 billion-year story. Placing 21st-century climate change in deep context, A Brief History of Earth is an indispensable look at where we’ve been and where we’re going.

Life in a Medieval City is the classic account of the year 1250 in the city of Troyes, in modern-day France. Acclaimed historians Frances and Joseph Gies focus on a high point of medieval civilization - before war and the Black Death ravaged Europe - providing a fascinating window into the sophistication of a period we too often dismiss as backward. Urban life in the Middle Ages revolved around the home, often a mixed-use dwelling for burghers with a store or workshop on the ground floor and living quarters upstairs.

Einstein’s Shadow follows a team of elite scientists on a historic mission to take the first picture of a black hole, putting Einstein’s theory of relativity to its ultimate test and helping to answer our deepest questions about space, time, the origins of the universe, and the nature of reality.

In August 1897, the young Belgian commandant Adrien de Gerlache set sail for a three-year expedition aboard the good ship Belgica with dreams of glory. His destination was the uncharted end of the earth: the icy continent of Antarctica. But de Gerlache’s plans to be first to the magnetic South Pole would swiftly go awry. After a series of costly setbacks, the commandant faced two bad options: turn back in defeat and spare his men the devastating Antarctic winter, or recklessly chase fame by sailing deeper into the freezing waters.

Between 1861 and 1865, the clash of the greatest armies the Western hemisphere had ever seen turned small towns, little-known streams, and obscure meadows in the American countryside into names we will always remember. In those great battles, those streams ran red with blood-and the United States was truly born.

In 1763, the painter Joshua Reynolds proposed to his friend Samuel Johnson that they invite a few friends to join them every Friday at the Turk's Head Tavern in London to dine, drink, and talk until midnight. Eventually, the group came to include among its members Edmund Burke, Adam Smith, Edward Gibbon, and James Boswell. It was known simply as "the Club". In this captivating audiobook, Leo Damrosch brings alive a brilliant, competitive, and eccentric cast of characters.

In Mycophilia, accomplished food writer and cookbook author Eugenia Bone examines the role of fungi as exotic delicacy, curative, poison, and hallucinogen, and ultimately discovers that a greater understanding of fungi is key to facing many challenges of the 21st century.

What won't we try in our quest for perfect health, beauty, and the fountain of youth? Well, just imagine a time when doctors prescribed morphine for crying infants. When liquefied gold was touted as immortality in a glass. And when strychnine - yes, that strychnine, the one used in rat poison - was dosed like Viagra. Looking back with fascination, horror, and not a little dash of dark, knowing humor, Quackery recounts the lively, at times unbelievable, history of medical misfires and malpractices.

The dramatic, pulse-pounding story of Harry Truman's first four months in office, when this unlikely president had to take on Germany, Japan, Stalin, and the atomic bomb, with the fate of the world hanging in the balance.

In The Last of His Kind, renowned adventure writer David Roberts gives readers a spellbinding history of mountain climbing in the twentieth century as told through the biography of Brad Washburn, legendary mountaineering pioneer and photographer. Jon Krakauer, author of Into Thin Air, has praised David Roberts, saying, “Nobody alive writes better about mountaineering” - and nowhere is that truth more evident than in this breathtaking account of the life and exploits of America’s greatest mountain climber.

It began as President Ulysses S. Grant's bid for international glory after the Civil War - America's first attempt to reach the North Pole. It ended with Captain Charles Hall's death under suspicious circumstances, dissension among sailors, scientists, and explorers, and the ship's evacuation and eventual sinking. Then came a brutal struggle for survival by 33 men, women, and children stranded on the polar ice.

What compels mountain climbers to take the risks that they do? Is it the thrill in the physical accomplishment, in managing to defy the odds, or both - and why do they continue to do what they do in the face of such great danger? In On the Ridge Between Life and Death, David Roberts confronts these questions head-on as he recounts the exhilarating highs and desperate lows of his climbing career.

By 1930, no place in the world was less well explored than Greenland. The native Inuit had occupied the relatively accessible west coast for centuries. The east coast, however, was another story. In August 1930, Henry George Watkins (nicknamed “Gino”), a twenty-three-year-old British explorer, led thirteen scientists and explorers on an ambitious expedition to the east coast of Greenland and into its vast and forbidding interior to set up a permanent meteorological base on the icecap, 8,200 feet above sea level.

On September 1, 2004, three middle-aged buddies set out on one of the last geographic challenges never before attempted in North America: to hike the Comb Ridge in one continuous push. The Comb is an upthrust ridge of sandstone-virtually a mini-mountain range-that stretches almost unbroken for a hundred miles from just east of Kayenta, Arizona, to some ten miles west of Blanding, Utah. To hike the Comb is to run a gauntlet of up-and-down severities, with the precipice lurking on one hand, the fiendishly convoluted bedrock slab on the other-always at a sideways, ankle-wrenching pitch.

The best-selling author of Black Flags, Blue Waters tells the story of a wild encounter between an American sealing vessel, a shipwrecked British brig, and a British warship in the Falkland Islands during the War of 1812. Fraught with misunderstandings and mistrust, the incident left three British sailors and two Americans including the captain of the sealer, Charles H. Barnard abandoned in the Falklands for eighteen months.

On January 17, 1913, alone and near starvation, Douglas Mawson, leader of the Australasian Antarctic Expedition, was hauling a sledge to get back to base camp - the dogs were gone. Mawson plunged through a snow bridge, dangling over an abyss by the sledge harness. A line of poetry gave him the will to haul himself back to the surface. On February 8, when he staggered back to base, his features unrecognizable, the first teammate to reach him blurted out, "Which one are you?"
