His cheeks are as tender as raw meat on a butcher's block. And those are just the cheeks of his face. As he slumps in the saddle, watching the road disappear into the distance, he aches in parts of his body that he's only just discovering he has. When Mark travels to Ecuador to go hiking and climbing, he discovers a land of dramatic volcanoes rising through the clouds and wide-open horizons rich in history.

For 18 years, Ed Viesturs pursued climbing's holy grail: to stand atop the world's 14 8,000-meter peaks, without the aid of bottled oxygen. But No Shortcuts to the Top is as much about the man who would become the first American to achieve that goal as it is about his stunning quest. As Viesturs recounts the stories of his most harrowing climbs, he reveals a man torn between the flat, safe world he and his loved ones share and the majestic and deadly places where only he can go.

There is but one aim: the summit, the summit of Mount Everest. What starts with a trouble-free trek into the Nepalese highlands explodes into a gripping tale of hardship, peril and adversity. Pushed beyond their physical and mental limits, climbers drop by the wayside. Their primal instincts for survival battle with their dogged resolve to drag themselves to the top of the world. But the focus remains: battle to the summit, and if successful, somehow get back down again. 

An SBS Gurkha soldier's account of how his tough Nepali upbringing and the lessons learned in his army life enabled his record-breaking conquest of all 14 of the world's 8,000m peaks in under seven months. What happens when ambition meets limitless imagination? Enter Project Possible: a seemingly unreachable goal to climb all 14 'death zone' mountains in record time. The previous record was seven years, 10 months and six days. I did it in six months. 

In 2014, Mount Everest was closed to all climbers after a devastating avalanche claimed the lives of 16 Nepali mountain workers ferrying loads up through the Khumbu Icefall on the mountain's southern approach through Nepal. Almost a year to the day later, in late April 2015, the mountain was once more rocked to its core after a large earthquake struck Nepal, sending shock waves rippling across the Himalayas.

On June 8th, 1924, George Mallory and 'Sandy' Irvine set out to stand on the roof of the world, where no one had stood before. They were last seen 800 feet shy of Everest's summit. A century later, we still don't know whether they achieved their goal, decades before Sir Edmund Hillary and Tensing Norgay did, in 1953. Irvine carried a Kodak camera with him to record their attempt, but it, along with his body, had never been found. Did Mallory and Irvine reach the summit and take a photograph before they fell to their deaths?

Joe Tasker lies, struck down by illness, in a damp, bug-infested room in the Himalaya, wondering if he will be well enough to climb Dunagiri, his first venture to the "big" mountains. One of Britain’s foremost mountaineers and a pioneer of lightweight climbing, he is about to attempt one of the first true "Alpine-style" climbs in the Greater Ranges. The Dunagiri attempt forms part of Tasker’s striking tale of adventure in the savage arena of the mountains.

Of all the games mountaineers play on the world’s high mountains, the hardest - and cruelest - is climbing the 14 peaks over 8,000 meters in the bitter cold of winter. Ferocious winds that can pick you up and throw you down, freezing temperatures that burn your lungs and numb your bones, weeks of psychological torment in dark isolation - these are adventures for those with an iron will and a ruthless determination.

On 30 January, 1981 Joe Tasker and Ade Burgess stood at 24,000 feet on the west ridge of Mount Everest. Below them were their companions, some exhausted, some crippled by illness, all virtually incapacitated. Further progress seemed impossible. Everest the Cruel Way is Joe Tasker's story of an attempt to climb the highest mountain on earth - an attempt which pushed a group of Britain's finest mountaineers to their limits. The goal had been to climb Mount Everest at its hardest: via the infamous west ridge, without supplementary oxygen and in winter.

In K2: Life and Death on the World's Most Dangerous Mountain, Viesturs explores the remarkable history of the mountain and of those who have attempted to conquer it. At the same time he probes K2's most memorable sagas in an attempt to illustrate the lessons learned by confronting the fundamental questions raised by mountaineering - questions of risk, ambition, loyalty to one's teammates, self-sacrifice, and the price of glory.

The Last Great Mountain tells the story of the first ascent of Kangchenjunga the third highest but reputedly the hardest mountain in the world. It was an astonishing achievement for a British team led by Everest veteran Charles Evans. Drawing on interviews, diaries and unpublished accounts, Mick Conefrey begins his story in 1905 with the disastrous first attempt on the mountain by a team led by Aleister Crowley, explores the three dramatic German expeditions of the the late 1920s and brings it all to a climax 50 years later with the first ascent by Joe Brown and George Band.  

In early May 2006, a young British climber named David Sharp lay dying near the top of Mount Everest while forty other climbers walked past him on their way to the summit. A week later, Lincoln Hall, a seasoned Australian climber, was left for dead near the same spot. Hall's death was reported around the world, but the next day he was found alive after spending the night on the upper mountain with no food and no shelter.

From 1931 to 1953, there was a race like no other. It was a race to the top of the world - a race primarily between Great Britain, Nazi Germany and the United States. Carried on across nearly the entire sweep of the Himalayas, it involved not only the greatest mountain climbers of the era, but statesmen and millionaires, world-class athletes and bona fide eccentrics, scientists and generals, obscure villagers and national heroes.

On 1 August, 2008, 18 climbers from across the world reached the summit of K2, the world's second-highest and most dangerous mountain - a peak that claims the life of one in every four climbers who attempt it. Over the course of 28 hours K2 had exacted a deadly toll: 11 lives were lost in a series of catastrophic accidents.

Nicknamed 'Mountain Man' by the Sunday Telegraph, James Forrest is the record-breaking adventurer who climbed every mountain in England and Wales in just six months - the fastest ever time. Solo and unsupported, he walked over 1,000 miles and ascended five times the height of Everest during his 446-peak challenge. And he did it all on his days off from work, proving it is possible to integrate an epic adventure into your everyday life.
