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.

Venus Plus X


Theodore Sturgeon - 1960
    Here, violence is a vague and improbable notion. Technology has triumphed over hunger, overpopulation, pollution, even time and space. But there is a change Charlie finds even more shocking: gender is a thing of the past.

As Charlie Johns explores Ledom and its people, he finds that the human precepts he holds dear are profane in this new world. But has Charlie learned all there is to know about this advanced society? And why are the Ledom so intent on gaining Charlie's approval? Unsettling, compelling, and no less than visionary, here is science fiction at its boldest: a novel whose wisdom and lyricism make it one of the most original and insightful speculations on gender ever produced.
