In a time much like that of early twentieth-century Earth, Klyd Farris, Head of the legendary House of Zeor and a Sime healer, goes into Gen Territory to become a doctor by Gen law. He falls in love with a Gen woman who is not at all what she seems. Ultimately, he must choose between his Sime heritage and his Gen love—a choice that will shape humanity's future destiny.
Publishers Weekly says: "House of Zeor created a fervent cult. This second novel of the mutated Simes and their symbiotic-vampire relationship will be welcomed."
