Reactivated (Bolt Eaters Trilogy Book 1)


Isaac Hooke - 2018
    A platoon trapped on a faraway world. Bloodthirsty aliens who will stop at nothing to bring humanity to its knees. Eric was happily retired. His consciousness resided inside the body of an advanced android. He had two beautiful female companions, a platoon of war hero friends, and the entire floor of an apartment building to call his own. He had paid his dues, having saved the world during his previous stint in the army, and now he could live out the rest of his life in peace and quiet. As an android, he expected that life to last a very long time. And then the army came knocking at his door again. Soon he and his platoon find themselves dispatched to an alien world. Piloting Devastators, mechs equipped with enough firepower to take down a small army, Eric and his platoon are scouting the planet ahead of a planned human invasion. When things start to go very wrong, and the platoon finds itself cut off from support and surrounded by enemies on all sides, Eric begins to wonder if it will truly be humanity doing the invading, and not the aliens. Book one of a standalone military science fiction trilogy, Reactivated ends in a cliffhanger. Book two, Reforged, is available now.

And why does she feel like she's being watched? Increasingly unnerved, Cass is overjoyed at the arrival of the formidable Setari.

Struggling with an unfamiliar language and culture, she must adapt to virtual classrooms, friends who can teleport, and the ingrained attitude that strays are backward and slow.

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?
