The collapse of The Flow, the interstellar pathway between the planets of the Interdependency, has accelerated. Entire star systems - and billions of people - are becoming cut off from the rest of human civilization. This collapse was foretold through scientific prediction...and yet, even as the evidence is obvious and insurmountable, many still try to rationalize, delay and profit from, these final days of one of the greatest empires humanity has ever known.

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.

Three hostile alien races have united against humanity, determined to halt our expansion into space. The mastermind behind this lethal alliance is a traitor - Charles Boutin. He was a Colonial Defence Force scientist with access to their biggest military secrets. Now the CDF's only hope is to discover Boutin's plan. Trouble is, Boutin's dead. As a supersoldier created from Boutin's own DNA, Jared Dirac may have answers.

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.

John Perry was living peacefully on one of humanity's colonies - until he and his wife were offered an opportunity these ex-supersoldiers couldn't resist. To come out of retirement and lead a new frontier world. However, once on the planet, they discover they've been betrayed. For this colony is a pawn in an interstellar game of war and diplomacy. Humanity's Colonial Union has pitched itself against a new, seemingly unstoppable alien alliance dedicated to ending all human colonization.

The people of Earth now know that the human Colonial Union has kept them ignorant of the dangerous universe around them. For generations the CU had defended humanity against hostile aliens, deliberately keeping Earth an ignorant backwater and a source of military recruits. Now the CU’s secrets are known to all. Other alien races have come on the scene and formed a new alliance - an alliance against the Colonial Union. And they’ve invited the people of Earth to join them. For a shaken and betrayed Earth, the choice isn't obvious or easy.

"I'm Zoe Boutin Perry: A colonist stranded on a deadly pioneer world. Holy icon to a race of aliens. A player in a interstellar chess match to save humanity. Seventeen years old. Everyone on Earth knows the tale I am part of. But you don't know my tale: I'm going to tell it to you now, the only way I know how: not straight but true, the whole thing, to try make you feel what I felt: the joy and terror and uncertainty, panic and wonder, despair and hope."

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.

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.

Hilketa is a frenetic and violent pastime where players attack each other with swords and hammers. The main goal of the game: obtain your opponent's head and carry it through the goalposts. With flesh and bone bodies, a sport like this would be impossible. But all the players are "threeps", robot-like bodies controlled by people with Haden's Syndrome, so anything goes. No one gets hurt, but the brutality is real, and the crowds love it. Until a star athlete drops dead on the playing field.

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.

Surrounded and outgunned, a group of private military contractors known as “Strange Company” find themselves on a remote planet at the edge of known space, and on the losing end of a bad contract. Orbital D-beam strikes, dropships bristling with auto-guns, missiles, and troops - even Monarch space marines in state-of-the-art advanced battle rattle - will try to prevent the company from reaching the exfil LZ and getting off-world.

Peacetime can be a rough adjustment for the battle-hardened Merry Band of Pirates. Especially when aliens don’t get the memo that the shooting is over.

Days after winning OASIS Founder James Halliday's contest, Wade Watts makes a discovery that changes everything. Hidden within Halliday's vaults, waiting for his heir to find, lies a technological advancement that will once again change the world and make the OASIS a thousand times more wondrous - and addictive - than even Wade dreamed possible. With it comes a new riddle and a new quest - a last Easter egg from Halliday, hinting at a mysterious prize. And an unexpected, impossibly powerful and dangerous new rival awaits, one who'll kill millions to get what he wants.

One thousand years later. Humanity has left Earth behind and is rapidly expanding throughout the galaxy under the banner of The Union, a white supremacist government who racially ‘purified’ the human race hundreds of years in the past. Living on the fringe of this twisted Fourth Reich society, Dark Horse - the only Black man in the Union - commandeers a vessel and scours the galaxy for his missing teammates under the guise of an Exo-Hunter, seeking out exo-planets to satiate the Union’s need for colonization.
