It was a fun read. The story had enough detail to keep it engaging, but not so much that it bogs down. I love reading vintage sci-fi because of the lack of gratuitous sex and violence. The cake analogy that runs through the book is one I learned at a very young age and it is still useful today.
Conqueror Richard Henry's leads the human forces controlling the planet Kazo. Overlord Bitool is the chief Kazo managing the occupation of earth. Henrys' son, Richard jr., is involved in a plot to overthrow Bitool. Fomina, Bitool's beloved mate, is Conqueror Henrys' trusted house-servant. And nothing is really complicated until humans and Kazos discover a third intelligent race in the galaxy, and try to bring them into the newly developing peace.
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.
