From the back cover of the Questar first edition: Mission Starchild - For one thousand years the spaceship Starchild has housed the sole survivors of Earth's most devastating war. The ship has been their protector and their prison, a world apparently drifting without rhyme of reason between the stars. The young LeAnne and Donivan are thrust through the Starchild's airlock - and discover some startling truths. For outside the ship waits not the vacuum of space but the forests and meadows of Earth itself. Their "starship" is actually an underground habitat built to shelter humanity until the nuclear-ravaged land becomes safe once again. And the planet is already swarming with a strange alien race... intelligent beings, technologically advanced, with weapons poised to annihilate mankind... interlopers fiercely determined to keep the earth for themselves!
