Earth has been dominated for 1,000 years by an alien invader—and man is an endangered species. From the handful of surviving humans a courageous leader emerges—Jonnie Goodboy Tyler, who challenges the invincible might of the alien Psychlo empire in a battle of epic scale, danger and intrigue with the fate of the Earth and of the universe in the tenuous balance.

    The sole legacy of that war was the weapon that ended it: the death machines, the BERSERKERS. Guided by self-aware computers more intelligent than any human, these world-sized battlecraft carved a swath of death through the galaxy--until they arrived at the outskirts of the fledgling Empire of Man.These are the stories of the frail creatures who must meet this monstrous and implacable enemy--and who, by fighting it to a standstill, become the saviors of all living things.

    And that was the good news. 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 come ships of a technologically advanced, aggressive culture, and BAM! There go the good old days, when humans only got killed 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. The UN Expeditionary Force hitched a ride on Kristang ships to fight the Ruhar, wherever our new allies thought we could be useful. So, I went from fighting with the US Army in Nigeria, to fighting in space. It was lies, all of it. We shouldn't even be fighting the Ruhar, they aren't our enemy, our allies are. I'd better start at the beginning....

    That made her just the right age: old enough to be used, young enough to be broken. Or so the slavers thought. But Sassy turned out to be a little different from your typical slave girl. Maybe it was her unusual physical strength. Maybe it was her friendship with the captured Fleet crewman. Maybe it was her spirit. Whatever it was, it wouldn't let her resign herself to the life of a slave. She bided her time, watched for her moment. Finally it came, and she escaped.But that was only the beginning for Sassinak. Now she's a Fleet Captain with a pirate-chasing ship of her own, and only one regret in her life: not enough pirates.

    Humanity has a chance. In the near future, an alien probe arrives on Earth with a pivotal mission—help humanity survive an impending invasion by an alien armada so massive it can blot out the stars, or leave the human race to certain extinction. Despite overwhelming odds, the probe recruits a young inventor named Marc Ibarra to plan a daring gambit. To weather the coming storm, Ibarra must build a space fleet strong enough to face an implacable foe in a battle against annihilation.

    the desperate, take-no-prisoners struggle that led humanity to Halo--the fall of the planet Reach. Now, brought to life for the first time, here is the full story of that glorious, doomed conflict.While the brutal Covenant juggernaut sweeps inexorably through space, intent on wiping out humankind, only one stronghold remains--the planet Reach. Practically on Earth's doorstep, it is the last military fortress to defy the onslaught. But the personnel here have another, higher priority: to prevent the Covenant from discovering the location of Earth.Outnumbered and outgunned, the soldiers seem to have little chance against the Covenant, but Reach holds a closely guarded secret. It is the training ground for the very first "super soldiers." Code-named SPARTANs, these highly advanced warriors, specially bioengineered and technologically augmented, are the best in the universe--quiet, professional, and deadly.Now, as the ferocious Covenant attack begins, a handful of SPARTANs stand ready to wage ultimate war. They will kill, they will be destroyed, but they will never surrender. And at least one of them--the SPARTAN known as Master Chief--will live to fight another day on a mysterious and ancient, artificial world called Halo...

     A NATION AT WAR: The United Stars of America.

Wonderful questions.  Now get ready for some answers.  Here is the science behind interstellar propulsion: reports from top tier scientists and engineers on starflight propulsion techniques that use only means and methods that we currently know are scientifically possible. Here are in-depth essays on antimatter containment, solar sails, and fusion propulsion. And the human consequences?  Here is speculation by a magnificent array of award-winning SF writers on what an interstellar voyage might look like, might feel like—might be like.  It’s an all-star cast abounding with Hugo and Nebula award winners: Ben Bova, Mike Resnick, Jack McDevitt, Michael Bishop, Sarah Hoyt and more.

    Dreaming that the real world could be a little more like the countless science-fiction books, movies, and videogames he’s spent his life consuming. Dreaming that one day, some fantastic, world-altering event will shatter the monotony of his humdrum existence and whisk him off on some grand space-faring adventure. But hey, there’s nothing wrong with a little escapism, right? After all, Zack tells himself, he knows the difference between fantasy and reality. He knows that here in the real world, aimless teenage gamers with anger issues don’t get chosen to save the universe. And then he sees the flying saucer. Even stranger, the alien ship he’s staring at is straight out of the videogame he plays every night, a hugely popular online flight simulator called Armada—in which gamers just happen to be protecting the earth from alien invaders. No, Zack hasn’t lost his mind. As impossible as it seems, what he’s seeing is all too real. And his skills—as well as those of millions of gamers across the world—are going to be needed to save the earth from what’s about to befall it. It’s Zack’s chance, at last, to play the hero. But even through the terror and exhilaration, he can’t help thinking back to all those science-fiction stories he grew up with, and wondering: Doesn’t something about this scenario seem a little…familiar? At once gleefully embracing and brilliantly subverting science-fiction conventions as only Ernest Cline could, Armada is a rollicking, surprising thriller, a classic coming of age adventure, and an alien invasion tale like nothing you’ve ever read before—one whose every page is infused with the pop-culture savvy that has helped make Ready Player One a phenomenon.

    They called him Charlie. He had big eyes, abundant body hair and fairly long nostrils. His skeletal body was found clad in a bright red spacesuit, hidden in a rocky grave. They didn't know who he was, how he got there, or what had killed him. All they knew was that his corpse was 50,000 years old; and that meant that this man had somehow lived long before he ever could have existed!
