House Of Zeor

The first published novel in this bestselling series asks the question: What if the basic human nature suddenly changed? Hugh Valleroy of the Gen Police undertakes a covert mission into Sime Territory to rescue the woman he loves from the Sime kidnappers who would use her to destroy his government. His protector and guide?--a Sime who carefully and deliberately plans to kill him!
The New York Times Book Review says of the Sime-Gen Series that It calls to mind the Frank Herbert of 'Dune' and the Walter M. Miller, Jr. of 'A Canticle for Leibowitz'.
