Restless in the islands, with Patricia going her separate way, Harrison and Teresa with their newborn daughter set sail for the mainland. Reaching L.A. after a harrowing trip, they find that Ken Strossman and Gary Rutledge have established a hill community with Harrison's palatial home as its center. But their existence there is tenuous, requiring a great deal of effort and ingenuity to maintain their independence in dealing with the latest anomaly of nature, a mutated raccoon, much larger and more aggressive then their predecessors--now thriving in the inner city. They along with the organized human predators--mainly the surviving members of the city gangs--now represent an even greater threat to the community's survival. Harrison and Teresa are caught up in the ongoing struggle, while at the same time they attempt to deal with the vagaries of their personal lives.
