The search of a millennium is over. Computers aboard Starship Omega find a planet with water and oxygen 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 two hundred years required to find another solar system so the journey must end. 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 on the home planet.
It is time to arouse prepare Pazz for life on Earth while cloned sister Kylina, now 22 not 12 as remembered by Pazz, can be kept in reserve. There is also Lunol, from a primitive preindustrial planet but he is male and doesn't count.
