At the height of a thunderstorm, Chris Danvers, amateur TV broadcaster, witnesses on his screen the vision of a gorgeously beautiful woman--a woman who doesn't speak English or any known foreign language. When he manages to reach her again, he makes an extraordinary discovery: Marvia inhabits a completely different plane of existence. She also possesses a marvelous singing voice spanning seven octaves. When Chris tries to exploit her talents, he finds himself prosecuted as a charlatan. And then the girl herself takes a hand... A science fiction rediscovery, published in book form for the very first time.
