The Child Goddess — Louise Marley

Anthropologist-priest Isabel Burke is called in by the ExtraSolar Corporation to travel to the barren planet of Virimund to investigate some unusual, seemingly human children, born on Virimund, who do not age, and comes to the aid of one mysterious little girl, captured by ExtraSolar, which hopes to discover the secret of her ageless existence.
