The Narian Predicament — Bob Berry

The Narians had a large problem. A team of geneticists developed a longevity treatment that had an unexpected side effect. After the treatment they were fertile from age 220 to 230 and then they had a birth rate of 2.37 children. Then the Enemy attacked. They suffered very heavy losses during the first ten years of the war, many who hadn't had children yet and their population was on the verge of collapse. They needed an ally who could breed faster than them. Some ninety five years into the war they discovered Earth and Humans. Tial was put in charge of recruiting Humans to populate twelve planets and aiding in their fight for survival against their implacable foe. She recruited Jill and John O'Niell. Jill turned into a very good stratigist. Their son, Damian O'Niell, developed a jink drive for the Narian's ships that was an immense help in the fight. The Enemy attacked in much larger numbers than before, threatening to overwhelm the allies.
