More Than Human


Theodore Sturgeon - 1953

There's Baby, who invented an antigravity engine while still in the cradle, and Gerry, who has everything it takes to run the world except for a conscience. Separately, they are talented freaks. Together, they compose a single organism that may represent the next step in evolution, and the final chapter in the history of the human race.In this genre-bending novel - among the first to have launched scifi into the arena of literature - one of the great imaginers of the twentieth century tells a story as mind-blowing as any controlled substance and as affecting as a glimpse into a stranger's soul. For as the protagonists of More Than Human struggle to find who they are and whether they are meant to help humanity or destroy it. Theodore Sturgeon explores questions of power and morality, individuality and belonging, with suspense, pathos, and a lyricism rarely seen in science fiction.

Ender's Game


Orson Scott Card - 1985
    The result of genetic experimentation, Ender may be the military genius Earth desperately needs in a war against an alien enemy seeking to destroy all human life. The only way to find out is to throw Ender into ever harsher training, to chip away and find the diamond inside, or destroy him utterly. Ender Wiggin is six years old when it begins. He will grow up fast.But Ender is not the only result of the experiment. The war with the Buggers has been raging for a hundred years, and the quest for the perfect general has been underway almost as long. Ender's two older siblings, Peter and Valentine, are every bit as unusual as he is, but in very different ways. While Peter was too uncontrollably violent, Valentine very nearly lacks the capability for violence altogether. Neither was found suitable for the military's purpose. But they are driven by their jealousy of Ender, and by their inbred drive for power. Peter seeks to control the political process, to become a ruler. Valentine's abilities turn more toward the subtle control of the beliefs of commoner and elite alike, through powerfully convincing essays. Hiding their youth and identities behind the anonymity of the computer networks, these two begin working together to shape the destiny of Earth-an Earth that has no future at all if their brother Ender fails.
