The Gods Themselves

by Isaac Asimov

In the twenty-second century Earth obtains limitless, free energy from a source science little understands: an exchange between Earth and a parallel universe, using a process devised by the aliens. But even free energy has a price. The transference process itself will eventually lead to the destruction of the Earth's Sun—and of Earth itself. Only a few know the terrifying truth—an outcast Earth scientist, a rebellious alien inhabitant of a dying planet, a lunar-born human intuitionist who senses the imminent annihilation of the Sun. They know the truth—but who will listen? They have foreseen the cost of abundant energy—but who will believe? These few beings, human and alien, hold the key to Earth's survival.

Foreigner

by C. J. Cherryh

It had been nearly five centuries since the starship Phoenix had become lost in space and had encountered the world of the atevi. On this world where law was kept by registered assassination, war between the humans and atevi was inevitable. Now, 200 years after that conflict, the sole human allowed into atevi society is marked for an assassin's bullet. . . .

A Fire Upon The Deep

by Vernor Vinge

A Fire Upon the Deep is the big, breakout book that fulfills the promise of Vinge's career to date: a gripping tale of galactic war told on a cosmic scale. Thousands of years hence, many races inhabit a universe where a mind's potential is determined by its location in space, from superintelligent entities in the Transcend, to the limited minds of the Unthinking Depths, where only simple creatures and technology can function. Nobody knows what strange force partitioned space into these "regions of thought," but when the warring Straumli realm use an ancient Transcendent artifact as a weapon, they unwittingly unleash an awesome power that destroys thousands of worlds and enslaves all natural and artificial intelligence. Fleeing the threat, a family of scientists, including two children, are taken captive by the Tines, an alien race with a harsh medieval culture, and used as pawns in a ruthless power struggle. A rescue mission, not entirely composed of humans, must rescue the children-and a secret that may save the rest of interstellar civilization. A Fire Upon The Deep is the winner of the 1993 Hugo Award for Best Novel.
