Characters: Way, WAY, too many to talk about here.
Plot: This novel is actually a collection of short story's edited to look like they have a thin plot.

Some people rebel, try to stop them from ruining the wonderful planet by making it in Earth's image. But when war breaks out on Earth, they leave.
