Alien Day. The date was Friday, the third of August. For some people the day was just beginning, for others it was the ending in a perfectly normal way.

Nine weeks later, civilization is on the edge of a breakdown more devastating than any nuclear war…

“With the defenses of the Southern Appalachians sundered, the only thing standing between the ravening Posleen hordes and the soft interior of the Cumberland Plateau are the veterans of the 555th Mobile Infantry.
Dropped into Rabun Pass, with a couple of million Posleen behind them and fourteen million to the front, the only question is which will run out first: power, bullets or bodies.
But they have a hole card: far to the north the shattered SheVa Nine, nicknamed “”Bun-Bun,”” is undergoing a facelift. Rising from its smoking ashes is a new weapon of war, armed with the most advanced weaponry Terra has ever produced, capable of facing both the Posleen hordes and their redoubtable space-cruisers. Capable of dealing out Hell as only SheVa Nine can.

“First Contact Was Friendly
When aliens trundled a gate to other worlds into the Solar System, the world reacted with awe, hope and fear. When the first aliens to come through, the Glatun, turned out to be peaceful traders, the world breathed a sigh of relief.
Who Controls the Orbitals, Controls the World
When the Horvath came through, they announced their ownership of us by dropping rocks on three cities and gutting them. Since then, they’ve held Terra as their own personal fiefdom. With their control of the orbitals, there’s no way to win and Earth’s governments have accepted the status quo.
Live Free or Die
To free the world from the grip of the Horvath is going to take an unlikely hero. A hero unwilling to back down to alien or human governments, unwilling to live in slavery and with enough hubris, if not stature, to think he can win.
Fortunately, there’s Tyler Vernon. And he has bigger plans than just getting rid of the Horvath.
Troy Rising is a book in three parts—Live Free or Die being the first part—detailing the freeing of Earth from alien conquerors, the first steps into space using off-world technologies and the creation of Troy, a thousand trillion ton battlestation designed to secure the Solar System.”

Starting over sucks.When we moved to West Virginia right before my senior year, I’d pretty much resigned myself to thick accents, dodgy internet access, and a whole lot of boring…. until I spotted my hot neighbor, with his looming height and eerie green eyes. Things were looking up.And then he opened his mouth.Daemon is infuriating. Arrogant. Stab-worthy. We do not get along. At all. But when a stranger attacks me and Daemon literally freezes time with a wave of his hand, well, something…unexpected happens.The hot alien living next door marks me.You heard me. Alien. Turns out Daemon and his sister have a galaxy of enemies wanting to steal their abilities, and Daemon’s touch has me lit up like the Vegas Strip. The only way I’m getting out of this alive is by sticking close to Daemon until my alien mojo fades.If I don’t kill him first, that is.

“One night in October when he was ten years old, Tyler Dupree stood in his back yard and watched the stars go out. They all flared into brilliance at once, then disappeared, replaced by a flat, empty black barrier. He and his best friends, Jason and Diane Lawton, had seen what became known as the Big Blackout. It would shape their lives.
The effect is worldwide. The sun is now a featureless disk―a heat source, rather than an astronomical object. The moon is gone, but tides remain. Not only have the world’s artificial satellites fallen out of orbit, their recovered remains are pitted and aged, as though they’d been in space far longer than their known lifespans. As Tyler, Jason, and Diane grow up, a space probe reveals a bizarre truth: The barrier is artificial, generated by huge alien artifacts. Time is passing faster outside the barrier than inside―more than a hundred million years per year on Earth. At this rate, the death throes of the sun are only about forty years in our future.
Jason, now a promising young scientist, devotes his life to working against this slow-moving apocalypse. Diane throws herself into hedonism, marrying a sinister cult leader who’s forged a new religion out of the fears of the masses.”

In this harrowing novel, the world’s cities have been reduced to cinder and ash and alien plants have overtaken the earth. The plants, able to grow the size of maples in only a month and eventually reach six hundred feet, have commandeered the world’s soil and are sucking even the Great Lakes dry. In northern Minnesota, Anderson, an aging farmer armed with a Bible in one hand and a gun in the other, desperately leads the reduced citizenry of a small town in a daily struggle for meager existence. Throw into this fray Jeremiah Orville, a marauding outsider bent on a bizarre and private revenge, and the fight to live becomes a daunting task.

In The Martian Chronicles, Ray Bradbury, America’s preeminent storyteller, imagines a place of hope, dreams, and metaphor— of crystal pillars and fossil seas—where a fine dust settles on the great empty cities of a vanished, devastated civilization. Earthmen conquer Mars and then are conquered by it, lulled by dangerous lies of comfort and familiarity, and enchanted by the lingering glamour of an ancient, mysterious native race. In this classic work of fiction, Bradbury exposes our ambitions, weaknesses, and ignorance in a strange and breathtaking world where man does not belong.

In the sleepy English village of Midwich, a mysterious silver object appears and all the inhabitants fall unconscious. A day later the object is gone and everyone awakens unharmed – except that all the women in the village are discovered to be pregnant.

They grow up too fast and their minds exhibit frightening abilities that give them control over others and brings them into conflict with the villagers just as a chilling realisation dawns on the world outside . . . The Midwich Cuckoos is the classic tale of aliens in our midst, exploring how we respond when confronted by those who are innately superior to us in every conceivable way.

One day in 1798, woodsmen in southern France returned from the forest having captured a naked boy. He had been running wild, digging for food, and was covered with scars. In the village square, people gathered around, gaping and jabbering in words the boy didn’t understand. And so began the curious public life of the boy known as the Savage of Aveyron, whose journey took him all the way to Paris. Though the wild boy’s world was forever changed, some things stayed the same: sometimes, when the mountain winds blew, “he looked up at the sky, made sounds deep in his throat, and gave great bursts of laughter.” In a moving work of narrative nonfiction that reads like a novel, Mary Losure invests another compelling story from history with vivid and arresting new life.

“The Galactic Hegemony has been around a long time, and it likes stability–the kind of stability that member species like the aggressive, carnivorous Shongairi tend to disturb. So when the Hegemony Survey Force encountered a world whose so-called “”sentients””—””humans,”” they called themselves—were almost as bad as the Shongairi themselves, it seemed reasonable to use the Shongairi to neutralize them before they could become a second threat to galactic peace. And if the Shongairi took a few knocks in the process, all the better.
Now, Earth is conquered. The Shongairi have arrived in force, and humanity’s cities lie in radioactive ruins. In mere minutes, more than half the human race has died.
Master Sergeant Stephen Buchevsky, who thought he was being rotated home from his latest tour in Afghanistan, finds himself instead prowling the back country of the Balkans, dodging alien patrols and trying to organize scattered survivors without getting killed. And in the southeastern US, firearms instructor and former Marine Dave Dvorak finds himself at the center of a growing network of resistance—putting his extended family at lethal risk, but what else can you do?
On the face of it, Buchevsky’s and Dvorak’s chances look bleak, as do prospects for the rest of the surviving human race. But it may well be that Shongairi and the Hegemony alike have underestimated the inhabitants of that strange planet called Earth…”

Who have scattered Earth’s last survivors. To stay alone is to stay alive, Cassie believes, until she meets Evan Walker. Beguiling and mysterious, Evan Walker may be Cassie’s only hope for rescuing her brother–or even saving herself. But Cassie must choose: between trust and despair, between defiance and surrender, between life and death. To give up or to get up.”

“Bill Masen, bandages over his wounded eyes, misses the most spectacular meteorite shower England has ever seen. Removing his bandages the next morning, he finds masses of sightless people wandering the city. He soon meets Josella, another lucky person who has retained her sight, and together they leave the city, aware that the safe, familiar world they knew a mere twenty-four hours before is gone forever.
But to survive in this post-apocalyptic world, one must survive the Triffids, strange plants that years before began appearing all over the world. The Triffids can grow to over seven feet tall, pull their roots from the ground to walk, and kill a man with one quick lash of their poisonous stingers. With society in shambles, they are now poised to prey on humankind. Wyndham chillingly anticipates bio-warfare and mass destruction, fifty years before their realization, in this prescient account of Cold War paranoia.”

“In order to develop a secure defense against a hostile alien race’s next attack, government agencies breed child geniuses and train them as soldiers. A brilliant young boy, Andrew “”Ender”” Wiggin lives with his kind but distant parents, his sadistic brother Peter, and the person he loves more than anyone else, his sister Valentine. Peter and Valentine were candidates for the soldier-training program but didn’t make the cut–young Ender is the Wiggin drafted to the orbiting Battle School for rigorous military training.
Ender’s skills make him a leader in school and respected in the Battle Room, where children play at mock battles in zero gravity. Yet growing up in an artificial community of young soldiers, Ender suffers greatly from isolation, rivalry from his peers, pressure from the adult teachers, and an unsettling fear of the alien invaders. His psychological battles include loneliness, fear that he is becoming like the cruel brother he remembers, and fanning the flames of devotion to his beloved sister.
Is Ender the general Earth needs? But Ender is not the only result of the genetic experiments. The war with the Buggers has been raging for a hundred years, and the quest for the perfect general has been underway for almost as long. Ender’s two older siblings are every bit as unusual as he is, but in very different ways. Between the three of them lie the abilities to remake a world. If the world survives, that is.”

The world’s frantic efforts to signal the aliens go unanswered. The first contact is hostile: the invaders blast a Soviet space station, seize the survivors, and then destroy every dam and installation on Earth with a hail of asteriods.
Now the conquerors are descending on the American heartland, demanding servile surrender–or death for all humans.”

“First came the news that a flying saucer had landed in Iowa. Then came the announcement that the whole thing was a hoax. End of story. Case closed.
Except that two agents of the most secret intelligence agency in the U.S. government were on the scene and disappeared without reporting in. And four more agents who were sent in also disappeared. So the head of the agency and his two top agents went in and managed to get out with their discovery: an invasion is underway by slug-like aliens who can touch a human and completely control his or her mind. What the humans know, they know. What the slugs want, no matter what, the human will do. And most of Iowa is already under their control.
Sam Cavanaugh was one of the agents who discovered the truth. Unfortunately, that was just before he was taken over by one of the aliens and began working for the invaders, with no will of his own. And he has just learned that a high official in the Treasury Department is now under control of the aliens. Since the Treasury Department includes the Secret Service, which safeguards the President of the United States, control of the entire nation is near at hand .”
