An improbable world beckons. We think we know Madagascar, but it's too big, too eccentric and too impenetrable to be truly understood. If it was stretched out across Europe, the islands would reach from London to Algiers, and yet its road network is barely bigger than tiny Jamaica's. There is no evidence of any human life until about 10,000 years ago, and, when eventually people settled, it was migrants from Borneo - 3,700 miles away - who came out on top.

This is the inspiring story of an ordinary guy who achieved two great goals that others had told him were impossible. First, he set a record for the longest automobile journey ever made around the world, during the course of which he blasted his way out of minefields, survived a breakdown atop the Peak of Death, came within seconds of being lynched in Pakistan, and lost three of the five men who started with him - two to disease, one to the Vietcong.

Hailed as a masterpiece of American travel writing, Blue Highways is an unforgettable journey along our nation's backroads. William Least Heat-Moon set out with little more than the need to put home behind him and a sense of curiosity about "those little towns that get on the map-if they get on at all-only because some cartographer has a blank space to fill: Remote, Oregon; Simplicity, Virginia; New Freedom, Pennsylvania; New Hope, Tennessee; Why, Arizona; Whynot, Mississippi." His adventures, his discoveries, and his recollections of the extraordinary people he encountered along the way amount to a revelation of the true American experience.

Gerald Durrell's last book, The Aye-Aye and I, records his final animal-collecting expedition, a trip to Madagascar in 1990, and his efforts to save the elusive and mythical lemuroid known as the Aye-Aye. Prompted by the country's radical deforestation and slash-and-burn agriculture, Durrell, his wife, and their team of zoologists embark on a mission to capture and conserve the species - distinguished by its "giant, chisel-like teeth", "round, hypnotic eyes", and large "spoon-like ears".

In All Things Must Fight to Live, Bryan Mealer takes listeners on a harrowing 2000 mile journey through Congo, where gun-toting militia still rape and kill with impunity. Amidst burnt-out battlefields where armies still wrestle for control, into the dark corners of the forests, and along the high savanna, where thousands have been slaughtered and quickly forgotten, Mealer searches for signs that Africa's most troubled state will soon rise from ruin.

When Rosamond Halsey Carr first arrived in Africa, she didn't realize that she would spend the rest of her life there. As a young fashion illustrator living in New York City in the 1940s, she seemed the least likely candidate for such a life of adventure. But marriage to a hunter-explorer took her to what was then the Belgian Congo, and divorce left her determined to stay on in neighboring Rwanda as the manager of a flower plantation.

When Daily Telegraph correspondent Tim Butcher was sent to cover Africa in 2000, he quickly became obsessed with the idea of recreating H. M. Stanley's famous expedition - and travelling alone. Despite warnings that his plan was suicidal, Butcher set out for the Congo's eastern border with just a rucksack and a few thousand dollars hidden in his boots.

Two modern adventurers sought a treasure possessed by the legendary "Wild Men of Borneo". One found riches. The other vanished forever into an endless jungle. Had he shed civilization - or lost his mind? Global headlines suspected murder. Lured by these mysteries, New York Times best-selling author Carl Hoffman journeyed to find the truth, discovering that nothing is as it seems in the world's last Eden, where the lines between sinner, saint, and myth converge.

Bewitched by Indonesia for twenty-five years, Elizabeth Pisani recently traveled 26,000 miles around the archipelago in search of the links that bind this impossibly disparate nation. Fearless and funny, Pisani shares her deck space with pigs and cows, bunks down in a sulfurous volcano, and takes tea with a corpse. Along the way, she observes Big Men with child brides, debates corruption and cannibalism, and ponders "sticky" traditions that cannot be erased.

In the autumn of 1988, Michael Palin set out from the Reform Club with an ambitious plan: to circumnavigate the world, following the route taken by Jules Verne's fictional hero Phileas Fogg 115 years earlier. The rules were simple. He had to make the journey in 80 days using only forms of transport that would have been available to Fogg.

In his most challenging journey to date, Palin tackles the Himalayas, the greatest mountain range on earth. It is a virtually unbroken wall of rock stretching 1,800 miles from the borders of Afghanistan to south-west China. Penetrated but never conquered, it remains the world's most majestic natural barrier, a magnificent wilderness that shapes the history and politics of Asia to this day.

Starting in November 2013 in a forest in Rwanda, where a modest spring spouts a trickle of clear, cold water, Levison Wood set forth on foot, aiming to become the first person to walk the entire length of the Nile. He followed the river for nine months, over 4,000 miles, through six nations - Rwanda, Tanzania, Uganda, South Sudan, the Republic of Sudan, and Egypt - to the Mediterranean coast.

In this extraordinary work of narrative reportage, Kapka Kassabova returns to Bulgaria to explore the border it shares with Turkey and Greece. When she was a child, the border zone was rumored to be an easier crossing point into the West than the Berlin Wall, and it swarmed with soldiers and spies. On holidays in the "Red Riviera" on the Black Sea, she remembers playing on the beach only miles from a bristling electrified fence whose barbs pointed inward toward the enemy: the citizens of the totalitarian regime.

Levison Wood's famous walking expeditions have taken him from the length of the Nile River to the peaks of the Himalayas, and in Walking the Americas, Wood chronicles his latest exhilarating adventure: a 1,800-mile trek across the spine of the Americas, through eight countries, from Mexico to Colombia. Beginning in the Yucatán, Wood's journey takes him from sleepy barrios to glamorous cities to ancient Mayan ruins lying unexcavated in the wilderness.

Drive Nacho Drive tells the hilarious and sometimes harrowing story of what happens when Brad and Sheena Van Orden trade in the American dream for a year on the roads of Central and South America aboard “Nacho”, their quirky and somewhat temperamental Volkswagen van. As a result of questionable decision-making skills and intermittent bad luck, Brad and Sheena repeatedly find themselves in over their heads.
