Hugo Award-winning author John Scalzi returns to his best-selling Old Man’s War universe with The End of All Things, the direct sequel to 2013’s The Human Division.

Humans expanded into space…only to find a universe populated with multiple alien species bent on their destruction. Thus was the Colonial Union formed, to help protect us from a hostile universe. The Colonial Union used the Earth and its excess population for colonists and soldiers. It was a good arrangement…for the Colonial Union. Then the Earth said: no more.

Now the Colonial Union is living on borrowed time – a couple of decades at most before the ranks of the Colonial Defense Forces are depleted and the struggling human colonies are vulnerable to the alien species who have been waiting for the first sign of weakness to drive humanity to ruin. And there’s another problem: a group, lurking in the darkness of space, playing human and alien against each other – and against their own kind – for their own unknown reasons.

In this collapsing universe, CDF Lieutenant Harry Wilson and the Colonial Union diplomats he works with race against the clock to discover who is behind attacks on the Union and on alien races, to seek peace with a suspicious, angry Earth, and to keep humanity’s union intact…or else risk oblivion and extinction – and the end of all things.

A blazingly inventive near-future thriller from the best-selling, Hugo Award-winning John Scalzi.

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.

A quarter of a century later, in a world shaped by what’s now known as “Haden’s syndrome”, rookie FBI agent Chris Shane is paired with veteran agent Leslie Vann. The two of them are assigned what appears to be a Haden-related murder at the Watergate Hotel, with a suspect who is an “integrator” – someone who can let the locked in borrow their bodies for a time. If the Integrator was carrying a Haden client, then naming the suspect for the murder becomes that much more complicated.

But “complicated” doesn’t begin to describe it. As Shane and Vann began to unravel the threads of the murder, it becomes clear that the real mystery – and the real crime – is bigger than anyone could have imagined.

Following the events of The Last Colony, John Scalzi tells the story of the fight to maintain the unity of the human race.

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.

Against such possibilities, managing the survival of the Colonial Union won’t be easy, either. It will take diplomatic finesse, political cunning…and a brilliant “B Team”, centered on the resourceful Lieutenant Harry Wilson, that can be deployed to deal with the unpredictable and unexpected things the universe throws at you when you’re struggling to preserve the unity of the human race.

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, who with the help of Brian Javna, a childhood friend turned artificial intelligence, scours the earth looking for the rare creature. And they find it, in the unknowing form of Robin Baker, pet store owner, whose genes contain traces of the sheep DNA. But there are others with plans for the sheep as well: Mercenaries employed by the military. Adherents of a secret religion based on the writings of a 21st century science-fiction author. And alien races, eager to start a revolution on their home world and a war on Earth.

To keep our planet from being enslaved, Harry will have to pull off the greatest diplomatic coup in history, a grand gambit that will take him from the halls of power to the lava-strewn battlefields of alien worlds. There’s only one chance to get it right, to save the life of Robin Baker – and to protect the future of humanity.

Retired from his fighting days, John Perry is now village ombudsman for a human colony on distant Huckleberry. With his wife, former Special Forces warrior Jane Sagan, he farms several acres, adjudicates local disputes, and enjoys watching his adopted daughter grow up.That is, until his and Jane’s past reaches out to bring them back into the game – as leaders of a new human colony, to be peopled by settlers from all the major human worlds, for a deep political purpose that will put Perry and Sagan back in the thick of interstellar politics, betrayal, and war.

The Ghost Brigades are the Special Forces of the Colonial Defense Forces, elite troops created from the DNA of the dead and turned into the perfect soldiers for the CDF’s toughest operations. They’re young, they’re fast and strong, and they’re totally without normal human qualms.For the universe is a dangerous place for humanity – and it’s about to become far more dangerous. Three races that humans have clashed with before have allied to halt our expansion into space. Their linchpin: the turncoat military scientist Charles Boutin, who knows the CDF’s biggest military secrets. To prevail, the CDF most find out why Boutin did what he did.

Jared Dirac is the only human who can provide answers – a superhuman hybrid, created from Boutin’s DNA, whose brain is uniquely able to access Boutin’s electronic memories. But when the memory transplant appears to fail, Jared is given over to the Ghost Brigades.

Jared begins as one of these perfect soldiers, but as memories begin to surface, he begins to intuit the reason’s for Boutin’s betrayal.

As Jared desperately hunts for his “father”, he must also come to grips with his own choices. Time is running out: the alliance is preparing its offensive, and some of them plan worse things than humanity’s mere military defeat.

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.

Earth itself is a backwater. The bulk of humanity’s resources are in the hands of the Colonial Defense Force. Everybody knows that when you reach retirement age, you can join the CDF. They don’t want young people; they want people who carry the knowledge and skills of decades of living. You’ll be taken off Earth and never allowed to return. You’ll serve two years at the front. And if you survive, you’ll be given a generous homestead stake of your own, on one of our hard-won colony planets.

John Perry is taking that deal. He has only the vaguest idea of what to expect. Because the actual fight, light-years from home, is far, far harder than he can imagine. And what he will become is far stranger.
