The Gods Themselves
Author: Isaac Asimov
Desc: 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 the Earth's survival.
