After the untimely death of his mentor, Berkeley physicist Joshua Andrews has dedicated himself to finishing his mentor’s life work: Creating entangled particles that can communicate faster than light. When scientific journalist Rachael Miller comes to interview him at his lab, they make an astounding discovery, one as ancient as the universe itself. During the early moments of the Big Bang, entangled particles were created that spread with the expansion of the universe creating a subatomic communication network - a network that Joshua and Rachael have accidentally tapped into.

Dr. Tyson Klein is a quantum physicist who has dedicated his entire life to his research. At CERN, he analyses data generated by the Large Hadron Collider, the world's biggest and most powerful particle accelerator. Now, Ty believes he's found a pattern in its output. It looks like an organised data stream, being broadcast over what he calls a quantum radio. Could it be a signal from another universe? A message sent from the future? Or something else entirely?

Colton Beck has six months to live. He works for the Angor near Los Angeles, aware that any day could be his last. The Angor arrived twenty years ago, resolved to help mankind survive, but not everyone believes their motives are honorable. When the Angor offer humanity a colony world, Colton is determined to see another planet before his final breath. He's been diagnosed with Xeno, a rare disorder that surfaced with the Angor's arrival, but he won't let this stop him.

Between 2017 and 2021, the US military admitted to having undeniable evidence that UFOs (now UAVs or UAPs) are here and defy the laws of physics. When Jason Ramsey, a popular science-fiction writer, becomes obsessed with the subject, he undertakes a relentless quest to uncover what is really going on. After recruiting Tessa Barrett, an extraordinarily talented mercenary, Jason devises a risky, desperate plan to get to the bottom of it all. But the truth is far more shocking, convoluted, and dangerous than anyone could have guessed, and he has no idea who he can trust.

Daniel Rice is a government science investigator whose specialty is solving seemingly intractable problems through scientific inquiry. But Daniel's intellectual strength is sorely tested by the bizarre realities he finds in the quantum world. Extra dimensions of space trap the unwary, probability replaces cause and effect, and time isn't what anyone imagined. The other side of the mirror is a place full of dangers, but it's also somewhere a dedicated scientist can uncover secrets that connect humans with something greater.

Geophysicist Jack Greer believes he may finally have found the resting place of the meteorite that wiped out the dinosaurs 65 million years ago. A few miles off the Yucatán coast, Jack and a team of scientists tow an aging drilling platform over the impact crater with the aim of securing a sample. But buried deep beneath the earth lies a shocking discovery that threatens to shatter everything we think we know about our species.

After a mysterious global event known only as “The Change”, six strangers wake up in an underground research facility where they learn that they’re part of the Extinction Trials - a scientific experiment to restart the human race. But the Extinction Trials harbors a very big secret. And so does the world outside.

When an experiment to study quantum uncertainty goes spectacularly wrong, physics student Bill Rustad and his friends find that they have accidentally created an inter-dimensional portal. They connect to Outland - an alternate Earth with identical geology, but where humans never evolved. The group races to establish control of the portal before the government, the military, or evildoers can take it away. Then everything changes when the Yellowstone supervolcano erupts in an explosion large enough to destroy civilization and kill half the planet.

Jack Kernigan is having a bad day...a bad year...a bad life. After being booted out of MIT, he’s back in his Ohio hometown, working for the family business, facing a life of mediocrity. Then one day, out on a delivery, his truck hits...something. Something big...something furry...something invisible. And, it turns out, something not of this Earth. Fate can play funny tricks. Which is why Jack suddenly finds himself the planet’s best hope to unravel a conspiracy of galactic proportions that could spell the end of the human race.

The Galahad, a faster-than-light spacecraft, carries 50 scientists and engineers on a mission to prepare Kepler 452b, Earth's nearest habitable neighbor at 1400 light years away. With Earth no longer habitable and the Mars colony slowly failing, they are humanity's best hope. After 10 years in a failed cryogenic bed - body asleep, mind awake - William Chanokh's torture comes to an end as the fog clears, the hatch opens, and his friend and fellow hacker, Tom, greets him...by stabbing a screwdriver into his heart. This is the first time William dies.

Jeff Dolan always wanted to be an astronaut. After helping a private space company build a ship that can travel to Saturn's largest moon in five months, he gets his chance. Shortly after launch, a devastating malfunction forces Jeff and the crew to make a choice: continue to Titan or go back home. As the truth about their mission unravels, one thing is clear: Someone on Earth knew about the system flaw and covered it up. Yet surviving the journey isn't the crew's only concern. Even if they make it to Titan, they will face another problem: Something is already there.

In 2018, Canadian archaeologist Ron Jackson makes a mind-boggling discovery in Antarctica - right before disappearing without a trace, leaving behind only his controversial theory that humans have lived on Earth far, far longer than we think they have. Decades later, in 2042, when Jackson's wife dies under mysterious circumstances, an unlikely pair of investigators, Agatha Devenworth and Pano Hofer, begin investigating whether her death might be connected to Jackson's disappearance.

There's a reason We Are Legion was named Audible's Best Science Fiction Book of 2016: Its irresistibly irreverent wit! Bob Johansson has just sold his software company for a small fortune and is looking forward to a life of leisure. The first item on his to-do list: Spending his newfound windfall. On an urge to splurge, he signs up to have his head cryogenically preserved in case of death. Then he gets himself killed crossing the street. Waking up 117 years later, Bob discovers his mind has been uploaded into a sentient space probe with the ability to replicate itself.

John Riley is a physicist who achieves his lifelong dream of unraveling the mysteries of anti-gravity, but along the way, also unwittingly discovers the secret of interstellar communication. When he and a small group of coworkers attempt to respond to an unexpected message, believing it to have originated from somewhere on Earth, they find more than they anticipate. The message is from deep space.

Noah Harris and Ashley Flynn are field agents for a powerful organization tasked with protecting humanity from the misuse of game-changing technology.
