John Perry did two things on his 75th birthday. First, he visited his wife's grave. Then he joined the army. The good news is that humanity finally made it into interstellar space. The bad news is that planets fit to live on are scarce - and alien races willing to fight us for them are common. So, we fight, to defend Earth and to stake our own claim to planetary real estate. Far from Earth, the war has been going on for decades: brutal, bloody, unyielding.

Our universe is ruled by physics, and faster-than-light travel is not possible - until the discovery of The Flow, an extradimensional field we can access at certain points in space-time that transports us to other worlds, around other stars. Humanity flows away from Earth, into space, and in time forgets our home world and creates a new empire, the Interdependency, whose ethos requires that no one human outpost can survive without the others. It's a hedge against interstellar war - and a system of control for the rulers of the empire.

The Ruhar hit us on Columbus Day. There we were, innocently drifting along the cosmos on our little blue marble, like the Native Americans in 1492. Over the horizon came ships of a technologically advanced, aggressive culture, and BAM! There went the good old days, when humans got killed only by each other. So, Columbus Day. It fits. When the morning sky twinkled again, this time with Kristang starships jumping in to hammer the Ruhar, we thought we were saved.

When Ivan Pritchard signs on as a newbie aboard the Mad Astra, it's his final, desperate stab at giving his wife and children the life they deserve. He can survive the hazing of his crewmates, and how many times, really, can near-zero g make you vomit? But there's another challenge looming out there, in the farthest reaches of human exploration, that will test every man, woman and AI on the ship - and will force Ivan to confront the very essence of what makes him human.

Ensign Andrew Dahl has just been assigned to the Universal Union Capital Ship Intrepid, flagship of the Universal Union since the year 2456. Life couldn’t be better…until Andrew begins to pick up on the facts that (1) every Away Mission involves some kind of lethal confrontation with alien forces; (2) the ship’s captain, its chief science officer, and the handsome Lieutenant Kerensky always survive these confrontations; and (3) at least one low-ranked crew member is, sadly, always killed.

Bob Johansson has just sold his software company and is looking forward to a life of leisure. There are places to go, books to read, and movies to watch. So it's a little unfair when he gets himself killed crossing the street. Bob wakes up a century later to find that corpsicles have been declared to be without rights, and he is now the property of the state. He has been uploaded into computer hardware and is slated to be the controlling AI in an interstellar probe looking for habitable planets.

Not too long from today, a new, highly contagious virus makes its way across the globe. Most who get sick experience nothing worse than flu, fever, and headaches. But for the unlucky one percent - and nearly five million souls in the United States alone - the disease causes "Lock In": Victims fully awake and aware, but unable to move or respond to stimulus. The disease affects young, old, rich, poor, people of every color and creed. The world changes to meet the challenge.

The Ember War, book 1: The Earth is doomed. Humanity has a chance. In the near future, an alien probe arrives on Earth with a pivotal mission: to determine if humanity has what it takes to survive the impending invasion by a merciless armada. The probe discovers Marc Ibarra, a young inventor who holds the key to a daring gambit that could save a fraction of Earth's population. Humanity's only chance lies with Ibarra's ability to keep a terrible secret and engineer the planet down the narrow path to survival.

From the Audie-nominated narrator of The Martian. In eleven years' time, a million members of an alien race will arrive at Earth. Years before they enter orbit, their approach will be announced by the flare of a thousand flames in the sky, their ships' huge engines burning hard to slow them from the vast speeds needed to cross interstellar space. These foreboding lights will shine in our night sky like new stars, getting ever brighter until they outshine even the sun, casting ominous shadows and banishing the night until they suddenly blink out.

A human diplomat creates an interstellar incident when he kills an alien diplomat in a most unusual way. To avoid war, Earth's government must find an equally unusual object: A type of sheep ("The Android's Dream"), used in the alien race's coronation ceremony. To find the sheep, the government turns to Harry Creek, ex-cop, war hero and hacker extraordinaire.

It's a simple story. Boy finds proof that reality is a computer program. Boy uses program to manipulate time and space. Boy gets in trouble. Boy flees back in time to Medieval England to live as a wizard while he tries to think of a way to fix things. Boy gets in more trouble. Oh, and boy meets girl at some point.

AD 2204. An alien shipwreck is discovered on a planet at the very limits of human expansion - so Security Director Feriton Kayne selects a team to investigate. The ship’s sinister cargo not only raises bewildering questions but could also foreshadow humanity’s extinction. It will be up to the team to bring back answers, and the consequences of this voyage will change everything. Back on Earth, we can now make deserts bloom and extend lifespans indefinitely, so humanity seems invulnerable. We therefore welcomed the Olyix to Earth when they contacted us. But were the Olyix a blessing or a curse?

In a world full to bursting with would-be heroes, Jim couldn't be less interested in saving the day. His fireballs fizzle. He's awfully grumpy. Plus, he's been dead for about 60 years. When a renegade necromancer wrenches him from eternal slumber and into a world gone terribly, bizarrely wrong, all Jim wants is to find a way to die properly, once and for all. On his side, he's got a few shambling corpses, an inept thief, and a powerful death wish. But he's up against tough odds....

Earth is dying. Thousands of workers, who live in the vast caves beneath Mars, mine the precious elements that will make the planet habitable. They are Earth’s only hope. Until the day Darrow learns that it’s a lie. Mars has been habitable - and inhabited - for generations. Darrow disguises himself and infiltrates their society, intent on taking them down. But the surface is a battlefield - and Darrow isn't the only one with an agenda.

In the 25th century, humans have conquered space. The advent of faster-than-light travel has opened up hundreds of habitable planets for colonization, and humans have exploited the virtually limitless space and resources for hundreds of years with impunity. So complacent have they become with the overabundance that armed conflict is a thing of the past, and their machines of war are obsolete and decrepit. What would happen if they were suddenly threatened by a terrifying new enemy?
