Triple Detente Author:Piers Anthony This is a book about a deal between three civilizations to curb their populations and rule one another in a round-robbin way. Unfortunately, it's main tenet is that population can be controlled through mass homicide (culling). It's greatif you're an overlord, but sucks if you are one of the culled. Still, it's a fun read.
Very strange book. Interesting in its relations between the three races mentioned, but the basis of the pacificaion of all three planets is mass genocide. The killings are justified in the story, with no counterpoint, leading me to wonder what point Anthony was trying to get across.
