April 25, 1986 in Chernobyl was a turning point in world history. The disaster not only changed the world’s perception of nuclear power and the science that spawned it, but also our understanding of the planet’s delicate ecology. With the images of the abandoned homes and playgrounds beyond the barbed wire of the 30-kilometer Exclusion Zone, the rusting graveyards of contaminated trucks and helicopters, the farmland lashed with black rain, the event fixed for all time the notion of radiation as an invisible killer.

A comprehensive catalog of the most devastating and deadly events-natural or man-made-in human history. If you follow the news it can seem like injury, sickness, and death are now constant, inescapable occurrences that threaten us every second of every day. But such catastrophic events - as terrible and frightening as they are - have been happening for as long as mankind has walked the Earth.... and even before. From ancient volcanoes and floods to epidemics of cholera and smallpox to Hitler's mass killings in the 20th century, humanity's continued existence has always seemed perilous.

The real stories behind the scenery of America’s national parks. For 12 years, Andrea Lankford lived in the biggest, most impressive national parks in the world, working a job she loved. She chaperoned baby sea turtles on their journey to sea. She pursued bad guys on her galloping patrol horse. She jumped into rescue helicopters bound for the heart of the Grand Canyon. She won arguments with bears. She slept with a few too many rattlesnakes. Hell yeah, it was the best job in the world! Fortunately, Andrea survived it.

The legendary annihilation in 1883 of the volcano-island of Krakatoa - the name has since become a byword for a cataclysmic disaster - was followed by an immense tsunami that killed nearly 40,000 people. Beyond the purely physical horrors of an event that has only very recently been properly understood, the eruption changed the world in more ways than could possibly be imagined. Dust swirled round die planet for years, causing temperatures to plummet and sunsets to turn vivid with lurid and unsettling displays of light.

A fast-paced, rollicking, behind-the-scenes account of how the GOP since the 1950s has encouraged and exploited extremism, bigotry, and paranoia to gain power, American Psychosis offers listeners a brisk, can-you-believe-it journey through the netherworld of far-right irrationality and the Republican Party’s interactions with the darkest forces in America.

This is the intimate story of 20 tsars and tsarinas, some touched by genius, some by madness, but all inspired by holy autocracy and imperial ambition. Simon Sebag Montefiore's gripping chronicle reveals their secret world of unlimited power and ruthless empire building, overshadowed by palace conspiracy, family rivalries, sexual decadence, and wild extravagance, with a global cast of adventurers, courtesans, revolutionaries, and poets, from Ivan the Terrible to Tolstoy and Pushkin.

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.

As the Allies raced to defeat Hitler, four men, all in the same unit, earned medal after medal for battlefield heroism. Maurice “Footsie” Britt, a former professional football player, became the very first American to receive every award for valor in a single war. Michael Daly was a West Point dropout who risked his neck over and over to keep his men alive. Keith Ware would one day become the first and only draftee in history to attain the rank of general before serving in Vietnam. In WWII, Ware owed his life to the finest soldier he ever commanded, a baby-faced Texan named Audie Murphy.

Beginning in the predawn hours of airports in the Northeast, we meet the ticket agents who unknowingly usher terrorists onto their flights, and the flight attendants inside the hijacked planes. In New York City, first responders confront a scene of unimaginable horror at the Twin Towers. From a secret bunker underneath the White House, officials watch for incoming planes on radar. Aboard the small number of unarmed fighter jets in the air, pilots make a pact to fly into a hijacked airliner if necessary to bring it down.

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.

Shots rang out in Savannah's grandest mansion in the misty,early morning hours of May 2, 1981. Was it murder or self-defense? For nearly a decade, the shooting and its aftermath reverberated throughout this hauntingly beautiful city of moss-hung oaks and shaded squares. John Berendt's sharply observed, suspenseful, and witty narrative flows like a thoroughly engrossing novel, and yet it is a work of nonfiction.

In February 1959, a group of nine experienced hikers in the Russian Ural Mountains died mysteriously on an elevation known as Dead Mountain. Eerie aspects of the incident—unexplained violent injuries, signs that they cut open and fled the tent without proper clothing or shoes, a strange final photograph taken by one of the hikers, and elevated levels of radiation found on some of their clothes—have led to decades of speculation over what really happened.

It began with plutonium, the first element ever manufactured in quantity by humans. Fearing that the Germans would be the first to weaponize the atom, the United States marshaled brilliant minds and seemingly inexhaustible bodies to find a way to create a nuclear chain reaction of inconceivable explosive power. In a matter of months, the Hanford nuclear facility was built to produce and weaponize the enigmatic and deadly new material that would fuel atomic bombs.

Defying both civil authorities and the Mormon establishment in Salt Lake City, the renegade leaders of these Taliban-like theocracies are zealots who answer only to God; some 40,000 people still practice polygamy in these communities. At the core of Krakauer’s book are brothers Ron and Dan Lafferty, who insist they received a commandment from God to kill a blameless woman and her baby girl. Beginning with a meticulously researched account of this appalling double murder, Krakauer constructs a bone-chilling narrative of messianic delusion, polygamy, savage violence, and unyielding faith.

Israel and Palestine: The Complete History seeks to explain the overall story of Israeli and Palestinian tensions and divisions in the region. Indeed, without properly understanding the full history of the area, it is impossible to understand the current situation.

In this illuminating audiobook, Tyson and coauthor James Trefil, a renowned physicist and science popularizer, take on the big questions that humanity has been posing for millennia - How did life begin? What is our place in the universe? Are we alone? - and provide answers based on the most current data, observations, and theories.

From launchpad explosions to a pernicious cricket infestation to the demanding management style of Musk himself, the rise of SpaceX was beset with challenges and far from inevitable.

Dr. Catherine Kleier invites us to open our eyes to the phenomenal world of plant life and to the process she calls “Natura Revelata”, the joy of celebrating and learning from the secrets of nature. As Dr. Kleier shares her knowledge with contagious excitement for her subject, she emphasizes the middle ground: Instead of focusing on cell microbiology or the study of ecosystems and habitats, she stresses the basic biology, function, and the amazing adaptations of the plants we see all around us.
