Eon


Greg Bear - 1985
    NASA, NATO, and the UN sent explorers to the asteroid's surface...and discovered marvels and mysteries to drive researchers mad.For the Stone was from space--but perhaps not our space; it came from the future-but perhaps not our future; and within the hollowed asteroid was Thistledown. The remains of a vanished civilization. A human--English, Russian, and Chinese-speaking--civilization. Seven vast chambers containing forests, lakes, rivers, hanging cities...And museums describing the Death; the catastrophic war that was about to occur; the horror and the long winter that would follow. But while scientists and politicians bickered about how to use the information to stop the Death, the Stone yielded a secret that made even Earth's survival pale into insignificance.

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. Venus Plus X is Theodore Sturgeon's brilliant evocation of a civilization for whom tensions between male and female and the human preoccupation with sex no longer exist. 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.

Gods of Night


David Mack - 2008
     Elsewhere, deep in the Gamma Quadrant, an ancient mystery is solved. One of Earth's first generation of starships, lost for centuries, has been found dead and empty on a desolate planet. But its discovery so far from home has raised disturbing questions, and the answers harken back to a struggle for survival that once tested a captain and her crew to the limits of their humanity. From that terrifying flashpoint begins an apocalyptic odyssey that will reach across time and space to reveal the past, define the future, and show three captains -- Jean-Luc Picard of the U.S.S. Enterprise, TM William Riker of the U.S.S. Titan, and Ezri Dax of the U.S.S Aventine -- that some destinies are inescapable.
