An interesting perspective on a case of political correctness and socialism carried too far as an expediency to prolong the survival of the human race. There are masters and virtual slaves who have been genetically altered to be more suited for the roles selected for them. As always throughout human history, there are those so avid and crazed for power over others they are willing to kill without mercy a massive amount of their fellow humans. Add to this mix aliens whose way of perceiving the universe, life and their role in it that is almost incomprehensible to humans. Somehow things must change and two of the greatest authors of science fiction have woven a tale that is hard to put down.
