Do "angels" exist? If so, are they heaven-sent or products of the human brain? After the publication of the bestseller The Third Man Factor, which examined the phenomenon of explorers who found themselves at the edge of death and experienced a benevolent presence that led them out of the impossible, John Geiger was inundated with firsthand accounts from people who had the same experience - a vivid presence that aided them as they faced crises ranging from physical and sexual assaults to automobile accidents, airplane crashes and more.

In the tradition of Educated and The Glass Castle, this shattering and poetic memoir from a brave new voice tells the story of the author’s experience in an apocalyptic cult, and how understanding the natural world was her key to escape—and survival.

We all love a mystery - but what about a mystery that has no solution? Delve into the shadowy world of unsolved disappearances and people who have vanished without a trace, never to be seen again. Such strange and chilling tales run the gamut of the terrifying and the bizarre and include crime victims, lost explorers, ships vanished at sea, outdoor disappearances, and supernatural mysteries that defy all explanation.

As a park ranger with the National Park Service's law enforcement team, Andrea Lankford led search and rescue missions in some of the most beautiful (and dangerous) landscapes across America, from Yosemite to the Grand Canyon. But though she had the support of the agency, Andrea grew frustrated with the service's bureaucratic idiosyncrasies, and left the force after twelve years. Two decades later, however, she stumbles across a mystery that pulls her right back where she left off: three young men have vanished from the Pacific Crest Trail.

In May 1996, two skilled backcountry leaders, Lollie Winans and Julie Williams, entered Virginia’s Shenandoah National Park for a week-long backcountry camping trip. The free-spirited and remarkable young couple had met and fallen in love the previous summer while working at a world-renowned outdoor program for women. During their final days in the park, they descended the narrow remnants of a trail and pitched their tent in a hidden spot. After the pair didn’t return home as planned, park rangers found a scene of horror at their campsite.

As war clouds darkened over Europe in 1914, a party led by Sir Ernest Shackleton set out to make the first crossing of the entire Antarctic continent via the Pole. But their initial optimism was short-lived as ice floes closed around their ship, gradually crushing it and marooning twenty-eight men on the polar ice. Alone in the world's most unforgiving environment, Shackleton and his team began a brutal quest for survival.

Destined to become a classic of adventure literature, The Last Season examines the extraordinary life of legendary backcountry ranger Randy Morgenson and his mysterious disappearance in California's unforgiving Sierra Nevada - mountains as perilous as they are beautiful. Eric Blehm's masterful work is a gripping detective story interwoven with the riveting biography of a complicated, original, and wholly fascinating man.

The study of sexual physiology has been a paying career or a diverting sideline for scientists as far-ranging as Leonardo da Vinci and James Watson. The research has taken place behind the closed doors of laboratories, brothels, MRI centers, pig farms, sex-toy R&D labs, and Alfred Kinsey's attic.

Mary Roach, "The funniest science writer in the country", devoted the past two years to stepping behind those doors. In Bonk, Roach shows us how and why sexual arousal and orgasm can be so hard to achieve and what science is doing to slowly make the bedroom a more satisfying place.

On a mountain somewhere above treeline, in some of the coldest and worst winter conditions imaginable, two men lie unconscious in the snow as explosive winds batter the nearby summits. In The Last Traverse: Tragedy and Resilience in the Winter Whites, Ty Gagne masterfully lays out the events that led up to an epic and legendary rescue attempt in severe and dangerous winter conditions in the White Mountains of New Hampshire. More than a cautionary tale, it is a tribute to all the volunteers and professionals who willingly put themselves in harm's way to save lives.

These are the stories that defy conventional logic. The proverbial vanished without a trace incidences, which happen a lot more (and a lot closer to your backyard) than almost anyone thinks. These are the missing whose situations are the hardest on loved ones left behind. The cases that are an embarrassment for park superintendents, rangers, and law enforcement charged with Search & Rescue.

Every time we eat, we have the power to radically transform the world we live in. Our choices can help alleviate the most pressing issues we face today: the climate crisis, infectious and chronic diseases, human exploitation and, of course, non-human exploitation. Undeniably, these issues can be uncomfortable to learn about but the benefits of doing so cannot be overstated. It is quite literally a matter of life and death.

In this work on a subject too often dismissed as paranormal or disreputable, Jeffrey Meldrum gives us the first book on Sasquatch to be written by a scientist with impeccable academic credentials. He gives an objective look at the facts in a field mined with hoaxes and sensationalism. Meldrum reports on the work of a team of experts from a wide variety of fields who were assembled to examine the evidence for a large, yet undiscovered, North American primate.

Barbara Butcher was early in her recovery from alcoholism when she found an unexpected lifeline: a job at the Medical Examiner’s Office in New York City. The second woman ever hired for the role of Death Investigator in Manhattan, she was the first to last more than three months. The work was gritty, demanding, morbid, and sometimes dangerous—and she loved it. In What the Dead Know, she writes with the kind of New York attitude and bravado you might expect from decades in the field, investigating more than 5,500 death scenes, 680 of which were homicides.

In the late nineteenth century, people were obsessed by one of the last unmapped areas of the globe: The North Pole. No one knew what existed beyond the fortress of ice rimming the northern oceans. On July 8, 1879, the USS Jeannette set sail from San Francisco to cheering crowds in the grip of "Arctic Fever." The ship sailed into uncharted seas, but soon was trapped in pack ice. Two years into the harrowing voyage, the hull was breached. Amid the rush of water and the shrieks of breaking wooden boards, the crew abandoned the ship.

On November 5, 1942, a U.S. cargo plane slammed into the Greenland ice cap. Four days later, a B-17 on the search-and-rescue mission also crashed. Miraculously, all nine men on the B-17 survived.

In December of 1914, the British Imperial Trans-Antarctic Expedition, led by Sir Ernest Shackleton, sailed from the island of South Georgia in the Southern Ocean. Its goal: the first overland crossing of Antarctica. Soon trapped in a prison of solid pack ice, the crew became engaged in a legendary fight against brutal cold, impenetrable ice, dwin­dl­ing food, and complete isolation.

In 1914, Sir Ernest Shackleton sailed south aboard the Endurance to be the first to cross Antarctica. Shackleton's endeavor is legend, but few know the astonishing story of the Ross Sea party, the support crew he dispatched to the opposite side of the continent to build a vital lifeline of food and fuel depots.

Combining accounts of legendary mountain ascents with vivid descriptions of his own forays into wild, high landscapes, Robert Macfarlane reveals how the mystery of the world's highest places has come to grip the Western imagination - and perennially draws legions of adventurers up the most perilous slopes. His story begins three centuries ago, when mountains were feared as the forbidding abodes of dragons and other mysterious beasts.

On October 12, 1972, a plane carrying a team of young rugby players crashed into the remote, snow-peaked Andes. Out of the 45 original passengers and crew, only 16 made it off the mountain alive. For 10 excruciating weeks, they suffered deprivations beyond imagining, confronting nature head-on at its most furious and inhospitable. And to survive, these men and women not only had to keep their faith; they had to make an impossible decision: Should they eat the flesh of their dead friends?
