In a time much like that of early twentieth-century Earth, Digen 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.
