Earth, the fantasy - the place where mankind originated, the storied vista of green, rolling hills and unblemished mountains and fields of amber grain waving in a light breeze. Earth, the reality - a junk world, a dirty, dangerous, rundown planet filled with detention camps, flop houses, taverns, human body parts factories, mobsters' palaces, and a lawless immigrant community of aliens and humans on the run. Ned believes the refugees from outer space have been interbreeding with cockroaches the size of dinosaurs. But Em is seeking asylum-she's slim and pretty, and she thinks that Earth-which her ancestors left centuries ago-is unbelievably primitive. And that includes Ned and his beliefs.
