Decision at Doona

Therefore Doona could be colonized only if an official survey established that the planet was both habitable and uninhabited.But Spacedep had made a mistake--Doona was inhabited. Now the colonists' choice was limited. Leave Doona and return to the teeming hell of an overpopulated Terra. Or kill the catlike Hrrubans. Or learn, for the first time in history, how to coexist with an alien race.

A dead physicist who just happens to be her cloned twin. A missing dataset that could change the interstellar balance of power and turn a cold war hot. And a mining “accident” that is starting to look more and more like murder...Suddenly Li is chasing a killer in an alien world miles underground where everyone has a secret.

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.

Great North Road


Peter F. Hamilton - 2012
    The keys to this empire belong to the powerful North family - composed of successive generations of clones. Yet these clones are not identical. For one thing, genetic errors have crept in with each generation. For another, the original three clone "brothers" have gone their separate ways, and the branches of the family are now friendly rivals more than allies. Or maybe not so friendly. At least that's what the murder of a North clone in the English city of Newcastle suggests to Detective Sidney Hurst. Sid is a solid investigator who'd like nothing better than to hand off this hot potato of a case. The way he figures it, whether he solves the crime or not, he'll make enough enemies to ruin his career. Yet Sid's case is about to take an unexpected turn: Because the circumstances of the murder bear an uncanny resemblance to a killing that took place years ago on the planet St. Libra, where a North clone and his entire household were slaughtered in cold blood.The convicted slayer, Angela Tramelo, has always claimed her innocence. And now it seems she may have been right. Because only the St. Libra killer could have committed the Newcastle crime. Problem is, Angela also claims that the murderer was an alien monster. Now Sid must navigate through a Byzantine minefield of competing interests within the police department and the world's political and economic elite...all the while hunting down a brutal killer poised to strike again. And on St. Libra, Angela, newly released from prison, joins a mission to hunt down the elusive alien, only to learn that the line between hunter and hunted is a thin one.
