Tchicaya is a Yielder, member of the faction that believes this "novo-vacuum" deserves study. The opposing Preservationists--among them Mariama, his first love--seek to save worlds and destroy the novo-vacuum. Discord heats to terrorist violence; then enmities and alliances are turned upside-down by a discovery that may mean the novo-vacuum is, instead, a new and very different universe--and one which may contain life.
