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.

Crossover


Joel Shepherd - 2001
    Cassandra is an experimental design — more intelligent, more creative, and far more dangerous than any that have preceded her. But with her intellect come questions, and a moral awakening. She deserts the League and heads incognito into the space of her former enemy, the Federation, in search of a new life. Her chosen world is Callay, and its enormous, decadent capital metropolis of Tanusha, where the concerns of the war are literally and figuratively so many light years away. But the war between the League and the Federation was ideological as much as political, with much of that ideological dispute regarding the very existence of artificial sentience and the rules that govern its creation. Cassandra discovers that even in Tanusha, the powerful entities of this bloody conflict have wound their tentacles. Many in the League and the Federation have cause to want her dead, and Cassandra’s history, inevitably, catches up with her. Cassandra finds herself at the mercy of a society whose values preclude her own right even to exist. But her presence in Tanusha reveals other fault lines, and when Federal agents attempt to assassinate the Callayan president, she finds herself thrust into the service of her former enemies, using her lethal skills to attempt to protect her former enemies from forces beyond their ability to control. As she struggles for her place and survival in a new world, Cassandra must forge new friendships with old enemies, while attempting to confront the most disturbing and deadly realities of her own existence

In the Balance


Harry Turtledove - 1994
    Machines soared through the air, churned through the seas, crawled across the surface, pushing ever forward, carrying death. Earth was engaged in titanic struggle. Germany, Russia, France, China, Japan: the maps were changing day by day. The hostilities spread in ever-widening ripples of destruction: Britain, Italy, Africa...The fate of the world hung in the balance. Then the real enemy came. Out of the dark of night, out of the soft glow of dawn, out of the clear blue sky came an invasion force the likes of which Earth had never known - and worldwar was truly joined. The invaders were inhuman and they were unstoppable. Their technology was far beyond our reach, and their goal was simple. Fleetlord Atvar had arrived to claim Earth for the Empire. Never before had Earth's people been more divided. Never had the need for unity been greater. And grudgingly, inexpertly, humanity took up the challenge. In this epic novel of alternate history, Harry Turtledove takes us around the globe. We roll with German panzers; watch the coast of Britain with the RAF; and welcome alien-liberators to the Warsaw ghetto. In tiny planes we skim the vast Russian steppe, and we push the envelope of technology in secret labs at the University of Chicago. Turtledove's saga covers all the Earth, and beyond, as mankind - in all its folly and glory - faces the ultimate threat; and a turning point in history shows us a past that never was and a future that could yet come to be...
