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.
