It is sometime in the future of genetic engineering, at the point at which, for a high enough price, one can buy physical and intellectual characteristics for one's fetus. This is the story of a young American couple of average means who have one "normal" son and are negotiating a supernorm status for their female fetus. The action centers around the stresses placed on the young family by the financial sacrifices required to engineer a daughter who would be able to compete in the growing population of engineered people. Husband and wife disagree increasingly, and ultimately the family breaks up over the wife's obsession with having a perfectly engineered child.
