Armada


Ernest Cline - 2015
    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.

The Last Human


Zack Jordan - 2020
    Most days, she's got other things on her mind. Like hiding her identity among the hundreds of alien species roaming the corridors of Watertower Station. Or making sure her adoptive mother doesn't casually eviscerate one of their neighbors. Again.And most days, she can almost accept that she'll never know the truth--that she'll never know why humanity was deemed too dangerous to exist. Or whether she really is--impossibly--the lone survivor of a species destroyed a millennium ago. That is, until an encounter with a bounty hunter and a miles-long kinetic projectile leaves her life and her perspective shattered.Thrown into the universe at the helm of a stolen ship--with the dubious assistance of a rebellious spacesuit, an android death enthusiast on his sixtieth lifetime, and a ball of fluff with an IQ in the thousands--Sarya begins to uncover an impossible truth. What if humanity's death and her own existence are simply two moves in a demented cosmic game, one played out by vast alien intellects? Stranger still, what if these mad gods are offering Sarya a seat at their table--and a second chance for humanity?The Last Human is a sneakily brilliant, gleefully oddball space-opera debut--a masterful play on perspective, intelligence, and free will, wrapped in a rollicking journey through a strange and crowded galaxy.

Terminal Alliance


Jim C. Hines - 2017
    This would have worked out better for all involved if they hadn’t arrived after a mutated plague wiped out half the planet, turned the rest into shambling, near-unstoppable animals, and basically destroyed human civilization. You know—your standard apocalypse. The Krakau’s first impulse was to turn their ships around and go home. After all, it’s hard to establish diplomatic relations with mindless savages who eat your diplomats. Their second impulse was to try to fix us. A century later, human beings might not be what they once were, but at least they’re no longer trying to eat everyone. Mostly.Marion “Mops” Adamopoulos is surprisingly bright (for a human). As a Lieutenant on the Earth Mercenary Corps Ship Pufferfish, she’s in charge of the Shipboard Hygiene and Sanitation team. When a bioweapon attack by an alien race wipes out the Krakau command crew and reverts the rest of the humans to their feral state, only Mops and her team are left with their minds intact.Escaping the attacking aliens—not to mention her shambling crewmates—is only the beginning. Sure, Mops and her assortment of space janitors and plumbers can clean the ship, but flying the damn thing is another matter.

Old Man's War


John Scalzi - 2005
    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 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.
