Destiny's End

'''Sullivan, Tim. Destiny's End.''' New York: Avon, 1988.

In a universe on the brink of collapse, materialistic humans build "a massive machine brain (an entire planet) dedicated for the search for immortality." More generally, see for organic machinery. Rev. R. A. Collins, SF&FBR Annual 1989: 418-19, source for this entry, and quote.
