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.

Fortune's Rising


Sara King - 2012

Alien vehicles left in panicked lines, sealed from the inside, no corpses within. Empty space stations, with no one to run them but the dust. Resources everywhere, ripe for the taking.But Fortune is different. Of all the planets colonized by humans after the chaos of Migration, this single, jungle-infested colony on the very edge of the known universe holds the key to the alien collapse…and to humanity’s survival. Everywhere else, advanced alien ruins mar every surface, every planetoid, every debris ring and asteroid, but of the creatures that made them, there is no sign. On Fortune, something survives…Unfortunately for humanity, while time is running out, a rebellion is brewing, one that could save our species—or consign it to dust like the aliens that came before us. Now, seven hundred years after our first brush with extinction, the fate of the human race once again rests on the shoulders of a few: a seven-year-old sociopath and her combat-gifted big sister, a man who’s dreamed of the future, an infamous smuggler, and a Coalition pilot sworn to destroy the rebel cause.This time, however, the stakes are higher.

Fear the Sky

Their technology is vastly superior to ours, and they know they cannot possibly lose the coming conflict. But they, like us, have found no answer to the destructive force of the atom, and they have no intention of facing the onslaught of our primitive nuclear arsenal, or the devastation it would wreak on the planet they crave. So they have flung out an advanced party in front of them, hidden within one of the countless asteroids randomly roaming the void. They do not want us, they want our planet. Their Agents are arriving.
