Lords of the Middle Dark

Chalker, Jack L. Lords of the Middle Dark. New York: Ballantine, 1986.

The Earth is ruled by a supercomputer (the Master System) designed to stop all warfare; the computer has reduced the level of human technology to the primitive. One of the few remaining technicians finds out how to stop the Master system while other people discover the key to controlling it. Rev. James T. Crawford, FR #94 (Sept. 1986): 21, source for this entry. Cf. and contrast Ursula K. Le Guin's City of Illusions (1967).
