Murder, politics, deception, and genetic and psychological manipulation combine against a backdrop of interstellar human societies at odds to create a mesmerizing and major work in Regenesis. Who did kill the original Ariane Emory? And can her personal replicate avoid the same fate? Those questions have remained unanswered for two decades - since the publication of Cyteen. Now in Regenesis those questions will finally be answered.
