Omega Seed

The search of a millennium is over. Computers aboard Intergalactic Starship Omega find a planet with water and oxygen in usable quantities to sustain humanoid life. It is over populated, polluted and has one social problem; forty eight percent of the human population are males, well beyond the one in a thousand necessary on Planet Delta to maintain the sperm banks. However, the humanoids aboard cannot be kept alive for the estimated two hundred years required to find another solar system so the journey must end.
Minor alterations are needed in the humanoids' metabolism. The women need to understand English for a landing in Australia, the most unpolluted continent the computers can find. Sensations and emotions are changed back to natural; after all, a bearer needs emotions more than the neuter that these females were, on the home planet. It is time to arouse Pazz and prepare her for life on Earth while cloned younger sister Kylina, now 22 not 12 as remembered by Pazz, can be kept in reserve.
There is also Lunol, from a primitive preindustrial planet and Kylina's partner but he is male and doesn't count. Alone, with only an armlet computer for company, Pazz lands in the West Australian desert. She catches the Indian Pacific Express for Sydney, three days journey away but catches the flu virus. With no immunity she becomes seriously ill and is taken off the train at Adelaide. Doctor Duncan Bourne a linguist from The University Of Adelaide is contacted when nobody can understand her delirious speech.
Duncan finds her speaking an ancient dead Greek language that he can understand. After she recovers, they become friends. Pazz adapts to life on Earth and, by having her qualifications entered into Earth computers, becomes Doctor Pazz D'rose, a mathematician and biochemist. How does this affect Pazz, Kylina and her partner? Is Lunol rescued and how do the military on Earth react to having the alien humans in their midst?
