The 1852 overland migration was the largest on record, with numbers swelled by Oregon-bound settlers as well as hordes of gold-seekers destined for California.

When Elon Musk was a kid in South Africa, he was regularly beaten by bullies. One day a group pushed him down some concrete steps and kicked him until his face was a swollen ball of flesh.

Adjusting his wealth to modern values, he was worth about an estimated $400 billion as the Sultan of ancient Mali, which controlled the trade routes across the Sahara Desert.

In the best-selling tradition of Bill Bryson and Tony Horwitz, Rinker Buck's The Oregon Trail is a major work of participatory history: an epic account of traveling the entire 2,000-mile length of the Oregon Trail the old-fashioned way, in a covered wagon with a team of mules - which hasn't been done in a century - that also tells the rich history of the trail, the people who made the migration, and its significance to the country.

When they returned two years later, they had long since been given up for dead.

"I am hopelessly and forever a mountaineer," John Muir wrote. "Civilization and fever and all the morbidness that has been hooted at me has not dimmed my glacial eye, and I care to live only to entice people to look at Nature's loveliness. My own special self is nothing". In Donald Worster's magisterial biography, John Muir's "special self" is fully explored as is his extraordinary ability, then and now, to get others to see the sacred beauty of the natural world.

Frederick Law Olmsted is arguably the most important historical figure that the average American knows the least about. Best remembered for his landscape architecture, from New York's Central Park to Boston's Emerald Necklace to Stanford University's campus, Olmsted was also an influential journalist, early voice for the environment, and abolitionist credited with helping dissuade England from joining the South in the Civil War. This momentous career was shadowed by a tragic personal life, also fully portrayed here.

To his contemporaries in Gilded Age Manhattan, Guillermo Eliseo was a fantastically wealthy Mexican, the proud owner of a luxury apartment overlooking Central Park, a busy Wall Street office, and scores of mines and haciendas in Mexico. But for all his obvious riches and his elegant appearance, Eliseo was also the possessor of a devastating secret: He was not, in fact, from Mexico at all. Rather, he had begun life as a slave named William Ellis, born on a cotton plantation in Texas during the waning years of King Cotton.

Two years ago, Graham Robb moved to a lonely house on the very edge of England, near the banks of a river that once marked the southern boundary of the legendary Debatable Land. The oldest detectable territorial division in Great Britain, the Debatable Land served as a buffer between Scotland and England. It was once the bloodiest region in the country, fought over by Henry VIII, Elizabeth I, and James V. After most of its population was slaughtered or deported, it became the last part of Great Britain to be brought under the control of the state.

At the end of 1618, a blazing green star soared across the night sky over the northern hemisphere. From the Philippines to the Arctic, the comet became a sensation and a symbol, a warning of doom or a promise of salvation. Two years later, as the Pilgrims prepared to sail across the Atlantic on board the Mayflower, the atmosphere remained charged with fear and expectation. Men and women readied themselves for war, pestilence, or divine retribution. Against this background, and amid deep economic depression, the Pilgrims conceived their enterprise of exile.
