"Petra's world is ending. Earth has been destroyed by a comet, and only a few hundred scientists and their children--among them Petra and her family--have been chosen to journey to a new planet. They are the ones who must carry on the human race.... Petra alone now carries the stories of our past, and with them, any hope for our future. Can she make them live again?"
"A keep-you-up-all-night, compulsively readable science fiction novel that offers much food for thought."
