This is the saga of humanity's destiny... Following a cataclysm, humanity has been divided into two mutant forms: the Simes and the Gens. Gens consider themselves to be the true humans, with little outward change, but their bodies produce selyn, an energy that Simes can't live without. The stronger and faster Simes develop the means to extract selyn from the Gens, a method that kills the Gen in the process. Gen communities are raided by Simes, the Gens rounded up and held in pens for Simes to use when needed. This is the saga of how these two disparate peoples learn to live as one. Sime Gen: The Unity Trilogy presents three classic novels of the future struggle of humanity: In House of Zeor by Jacqueline Lichtenberg, Hugh Valleroy, a Gen, must rescue the woman he loves from Sime raiders. To do so, he must learn to cooperate with and trust a renegade Sime, leader of the infamous House of Zeor.

Can she admit the truth of this discovery? In Zelerod's Doom by Lichtenberg and Lorrah
