DAYBREAK 2250 A.D.
It is almost 200 years since the global destruction wrought by nuclear war. The tools of man's technology lie rusting alongside the roads between ruined cities. In the mountains, the descendants of people who were training to colonize other worlds when war broke out, struggle to survive. But in their zeal to maintain the purity of the human race in the face of radiation-caused genetic mutations, the Tribe of the Eyrie have isolated and even killed those with characteristics that drift from the norm of humanity. Onto this stage steps a young man named Fors. The son of an honored explorer, a Star Man, has been denied the honor of becoming what his father had been, the courageous explorers who went into the lowlands searching the moldering cities for technology and devices to help their people survive, and more importantly, knowledge of what happened and why. Bitter and angry at the tribe's rejection, Fors leaves the mountain stronghold of his people and sets out alone on a trail that will change the history of not only his tribe, but all that remains of the human race.
Andre Norton's book, originally titled "Star Man's Son," foretells a cautionary tale of the future, one in which humans still have not learned the lessons of the past. The journey of Fors is a fascinating depiction of what the world would be like after the last great war of technology. In this world, the survivors of the human race have separated into tribes, each jealously guarding a swath of territory. Relationships between the tribes are bound in suspicion and conflict, but the real hatred is shared by all for the dwellers of the urban ruins, a human-rat hybrid known as the Beast Things.
Although all of the human tribes strive to turn their backs on those characteristics which drove their ancestors, known universally as The Old Ones, to war and destruction. But as the situation has developed, Norton makes it clear that conflict is an irrefutable part of the human make-up and despite the naive desire for "world peace," it would seem that humans will always reach first for the spear. The climax of the book, when the tribes gather for one last great battle against each other, becomes the moment when Fors steps forward and restores peace. He reminds all present that everyone faces a common enemy in the Beast Things and if humanity is to survive, that they must all band together in mutual support, or by choosing to exterminate each other, leave the planet to the Beast Things.
Andre (AKA Mary) Norton. Man I read a lot her books as a kid. I wonder if this is in a box of books in the basement. May have to check sometime.
