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.

Remnant Population

But while her fellow colonists grudgingly anticipate a difficult readjustment on some distant world, Ofelia savors the promise of a golden opportunity. Not starting over in the hurly-burly of a new community... but closing out her life in blissful solitude, in the place she has no intention of leaving. A population of one.With everything she needs to sustain her, and her independent spirit to buoy her, Ofelia actually does start life over–for the first time on her own terms: free of the demands, the judgments, and the petty tyrannies of others. But when a reconnaissance ship returns to her idyllic domain, and its crew is mysteriously slaughtered, Ofelia realizes she is not the sole inhabitant of her paradise after all. And, when the inevitable time of first contact finally arrives, she will find her life changed yet again–in ways she could never have imagined...
