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.

At 75 years old, John Perry is after a fresh start - so, naturally, he joins the army. Earth's military machine can transform elderly recruits, restoring their lost youth. But in return, its Colonial Defence Force demands two years of hazardous service in space. This is how Perry finds himself in a new body crafted from his original DNA. A genetically enhanced and upgraded new body, ready for battle. But upgrades alone won't keep Perry safe. He'll be fighting for his life on the front line as he defends humanity's colonies.

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.

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 question is, how can you tell the President's brain is missing? And are we sure we need it back? 

In John Scalzi's re-imagining of H. Beam Piper's 1962 sci-fi classic Little Fuzzy, written with the full cooperation of the Piper Estate, Jack Holloway works alone for reasons he doesnt care to talk about. Hundreds of miles from ZaraCorps headquarters on planet, 178 light-years from the corporations headquarters on Earth, Jack is content as an independent contractor, prospecting and surveying at his own pace. As for his past, thats not up for discussion.

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.

In the 20th century Earth sent probes, transmissions, and welcoming messages to the stars. Unfortunately, someone noticed. The Galactics arrived with their battle fleet in 2052. Rather than being exterminated under a barrage of hell-burners, Earth joined their vast Empire. Swearing allegiance to our distant alien overlords wasn't the only requirement for survival. We also had to have something of value to trade, something that neighboring planets would pay their hard-earned credits to buy. As most of the local worlds were too civilized to have a proper army, the only valuable service Earth could provide came in the form of soldiers....

Jon Ryan is irreverent, cocky, funny, and walks with a swagger. The cocky fighter pilot turned astronaut is also Earth's only chance for survival. The planet Jupiter, thrown off orbit, will destroy Earth in less than a century. Jon volunteers for the most ambitious, desperate mission ever conceived: His consciousness must be transferred into an experimental android host, where he'll live an immortal - and lonely - life. Jon's only companion on his 50-year voyage is his ship's irritable AI.

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?

Humanity has colonized the planets - interstellar travel is still beyond our reach, but the solar system has become a dense network of colonies. But there are tensions - the mineral-rich outer planets resent their dependence on Earth and Mars and the political and military clout they wield over the Belt and beyond. Now, when Captain Jim Holden's ice miner stumbles across a derelict, abandoned ship, he uncovers a secret that threatens to throw the entire system into war.

Belisarius is a quantum man, an engineered Homo quantus who fled the powerful insight of dangerously addictive quantum senses. He found a precarious balance as a con man, but when a client offers him untold wealth to move a squadron of warships across an enemy wormhole, he must embrace his birthright to even try. In fact, the job is so big that he'll need a crew built from all the new sub-branches of humanity. If he succeeds, he might trigger an interstellar war, but success might also point the way to the next step of Homo quantus evolution.
