Justifiable Genocide

It has been forty years since the Molodni attacked Earth in an attempt to eliminate humanity from the planet. They would have succeeded if not for one very ancient gene carried by only a select few people. After the Molodni attacking force was destroyed by a human mind-meld, the surviving members of humanity have come together in small groups around the world to attempt to survive and hopefully keep humanity alive and growing. They are suceeding slowly but surely. But the effort and diligence required to survive in a now untamed world have caused the Molodni attack to be shunted to the mental 'back burner', something to be thought of only occasionally by the survivors. And even less so by their offspring. But the Molodni on their home world near the center of the galaxy are still fiercely determined to take over the Earth, and eliminate those pesky humans while they are at it. In fact, preparations for their next attack are already underway. It will be a fight to the death for humanity The humans and the Molodni are unaware that BOTH civilizations will end up fighting for their very existence.
