The George Turner series continues.
Raw Feed (1992): Brain Child, George Turner, 1991.

This book truly deserves the distinction of being called a masterpiece. That distinction is almost solely because of Turner’s incredible skill with characterization (making him, in the science fiction field, probably the best in this area along with Philip K. Dick).
Turner’s plot in this novel of genetically engineered superintelligence is (according to my reading of the “Superman” entry in The Encyclopedia of Science Fiction) [that would, of course, be the massive second edition before it went online] typical of the sub-genre of the superman:
- The superman gracefully opts out of human society (the A Group).
- The superman has a fatal flaw which is the result of the creation process (the B Group’s death by sudden Alzheimer’s).
- The superman can’t stand to live on a planet of ignorant savages (C Group’s suicide).
