Parasite Planet: The Golden Amazon Saga, Book Nine

Reaching another solar system, the three Cosmic Crusaders discover a fantastic world of mental parasites drawing form and substance from our own Earth, fifty light years away. The planet is ruled by a being identical to the Golden Amazon herself--but an "Amazon" that is coldly scientific and vicious, mirroring the original Amazon as she had once been early in her career. They become locked in a deadly duel, and the Amazon and Abna are marooned by the double on a planet of monsters. And while the pair fight to survive, Viona becomes engaged to Mexone, a human inhabitant of another planet in the same system--only to face death with her fiancé as the Amazon II seeks to electrocute them. Can the Amazon and Abna escape from their prison world in time to rescue their daughter? Great action adventure from the golden age of science fiction!
