This is one of the most thought provoking books I have ever read. This is not a single novel, but rather a series of short stories on a single theme. That theme is a species of primates discovered in America, which are just called, "Simps."
The first story begins with the English beginning to colonize America in the 1600's. Much to their suprise, they discover a species of ape which walks on it's two hind legs, covered with short hair, and is very gentle. It looks almost human, but does not speak, and cannot understand speech. Still they seem highly intelligent and some are soon trained to perform simple tasks around the camp. Soon the question is raised, "Are the Simps human, or animals?" And that is the question which is raised in each chapter. The development of this country closely parallels our own American, each chapter moving forward a century or so. And as society develops and changes, does their relationship to the Simps, into the 21st century, when mankind has learned the Simps can be taken into the house, and used as servants to perform simple chores.
This book stimulates your grey cells so much it is almost painful. What is a human, and what ultimately defines us?
