The wild and free world of the mountain man is quickly fading into the past. For Titus Bass, leading his family north to winter with the Crow people, the journey is a sad one. He must save an old friend from death and rescue his daughter Magpie from cutthroat traders. He will try to free a wagon train of innocents from its unscrupulous leader, and he will try to come to terms with his long–lost daughter Amanda, bound for a new home in a faraway land Bass himself will never see.

Drawn by the promise of adventure and wealth, Titus Bass joins an expedition to Spanish California, where the ranchos have horses and mules in abundance. Their plan is to steal the livestock and drive it back east across the great Mojave Desert to sell to fur traders for top dollar. But pursuit by formidable Mexican soldiers and an attack by fierce Digger Indians take their toll on Bass and his fellow raiders.

When it comes to reducing animal suffering, many people aren’t sure where to start or which options are most beneficial. Charitable donations? Volunteer work? Dining at vegan restaurants? Meatless Mondays? The truth is that you have far more power than you think to make a real difference. Inspired by the effective altruism movement, The Impactful Vegan teaches listeners how to audit their impact and follow methods that have been scrutinized, evaluated, and determined to do the most good for animals.

This audiobook, Tomorrow's Medicine, looks at some of the more fascinating areas where technology that could transform health is being developed, including cybernetics, regenerative medicine, nanotechnology, and genetically tailored treatments. Although many of these advances may not be ready to treat humans for many years, some of them may someday profoundly change - and extend - our lives. As exciting as the possibilities are to extend both the length and quality of life, immortality - or at least agelessness - may be forever out of our reach.

In the two decades since astronomers first discovered the existence of a planet outside of our solar system, “exoplanetology” has become the hottest specialty in astrophysics. Scientists young and old, inspired by the thought of finding either another habitable world or the Holy Grail of space exploration - life itself - flocked to be part of this burgeoning field. With so much brainpower on hand, it’s no wonder that investigative techniques advanced more quickly than anyone would have thought.

It has been argued that science fiction (SF) gives a kind of weather forecast - not the telling of a fortune but rather the rough feeling of what the future might be like. The intention in this audiobook is to consider some of these bygone forecasts made by SF and to use this as a prism through which to view current developments in science and technology.

In the 25th century, the effects of overpopulation and global warming on Earth have led to the formation of human colonies on the Moon, Mars, and elsewhere in the solar system, yet the limited number of viable places forces humanity to look to the stars. A crash program has been developed to send Protos 1, a giant multigenerational starship, to a newly discovered Earth-like planet orbiting a nearby star.

Garbage comes to life as animated creatures called junklets, wreaking havoc in elementary schools. Specially trained kids from the magical School of Garbage are sent to stop the rise of the trash monsters. With the school’s magical janitorial supplies—brooms that can fly, toilet plungers that can reverse gravity, and mops that can capture anything in their strings—the ordinary becomes extraordinary.

One of America’s greatest success stories is its economy. For over a century, it has been the envy of the world. The opportunity it generates has inspired millions of people to want to become American. Today, however, America’s economy is at a crossroads. Across the political spectrum, many want the government to play an even greater role in the economy via protectionism, stakeholder capitalism, or even quasi-socialist policies. But managed decline and creeping statism do not have to be America’s only choices, let alone its destiny. This audiobook insists there is an alternative.

Endometriosis is a physically and mentally debilitating disease that has tortured women for centuries. Symptoms of heavy periods and excruciating pain most often begin in middle school or high school, yet doctors take an average of 12 years to diagnose it in a patient. As a result, these undiagnosed and misdiagnosed women suffer into at least their mid-20s or early 30s, repeatedly told that the pain is in their minds, that it’s simply part of becoming a woman, or that it’s caused by some other disease or condition. That nonsense must stop, and it must stop now!

Graysen Foxx is no stranger to the mysteries hidden in Ordinary Elementary—the bat-filled tunnels, the secret passageways, the underground chambers, and the sticky spiderwebs—and he’s on the hunt for a creepy old painting that will guarantee his victory in the school’s Halloween room contest. But finding and claiming the painting is only the beginning of a wild adventure filled with puzzles that will put Graysen’s treasure-hunting skills to the test. When Graysen finds a mysterious symbol on the back of a dusty spelling bee medal, the discovery spreads like creamy peanut butter.

Rob Sand, the youngest attorney in his office, was assigned a new case by his boss, who was days away from retirement. Inside the thin accordion binder that Sand received was meager evidence that had been gathered over the course of two years by Iowa authorities regarding a suspicious lottery ticket. No one expected the case to go anywhere. No dead body, no shots fired, and no money paid out. Why should they care?

The sense of position and movement is often called the sixth sense; the brain’s connection to the immune system might be a seventh. In this audiobook, we examine the diverse functions of the brain beyond the five senses, including the glymphatic system for maintaining brain health, the processes behind intuition, and new research raising questions about “brain death.”

Since the Industrial Revolution, our civilization has depended on fossil fuels for energy - first it was coal; then petroleum. If business as usual continues, we are looking at a world where sea levels will be high enough to submerge many coastal cities and extreme weather events like 2012’s Hurricane Sandy are the new normal. In this audiobook, The Future of Energy: Earth, Wind, and Fire, we review the energy problem and analyze the options from the mundane to the far out.

In science fiction, artificial intelligence takes the shape of computers that can speak like people, think for themselves, and sometimes act against us. Reality of course is vastly different, though in many ways computers surpass their fictional counterparts. This book reviews work in the field and covers topics from chess-playing to quantum computing. The writers tackle how to make computers more powerful, how we define consciousness, what the hard problems are, and even how computers might be built once the limits of silicon chips have been reached.

Instead of “what if the South won the Civil War?” cosmologists ask, “what if the constants that make up the fundamental building blocks of physics were different?” Physicists argue that any slight change to the laws of physics would mean a disruption in the evolution of the universe - and our existence. With the many factors that had to align for us to exist, it can seem like the laws of physics might seem finely tuned to make our existence possible. Instead of a supernatural or divine explanation, this book explores the possibility is that our universe isn’t the only one.

Paper Belt on Fire is the unlikely account of how two outsiders with no experience in finance—a charter school principal and defrocked philosopher—start a venture capital fund to short the higher education bubble. Against the contempt of the education establishment, they discover, mentor, and back the leading lights in the next generation of dropout innovators and in the end make their investors millions. Can such a madcap strategy help renew American creativity? This story is the behind-the-scenes romp of one team that threw educational authorities into a panic.

Our nearest planetary neighbor has been the subject of endless fascination and wide-ranging theories throughout history. Is there life on Mars? Was there ever life on Mars? What was the atmosphere like thousands or millions of years ago? From Percival Lowell, who built his own observatory so he could dedicate himself to studying the red planet, to NASA landing the car-sized Curiosity rover in 2012, this book traces Scientific American's coverage of the observation and exploration of Mars.

The nuclear bomb ushered in a new age. The rules of warfare had to change when one act might end civilization. In this audiobook, The Changing Face of War, we examine the technologies being developed or adapted for war and defense - and what these innovations mean for the way nations (and non-state antagonists) conduct military or security operations.

The Book of Revelation, the Maya, Nostradamus - humans have speculated about the end since, well, the beginning. In this book, we look at several “end of the world” scenarios - or at least, things that could make human life really difficult.
