Asimov’s Foundation Trilogy was some of the first adult science fiction I read when I was a kid. Revisiting it was like meeting an old friend at a reunion. This prequel to the series, written 35 years after the trilogy but previous to it, tells of the early life of Hari Seldon, the man who invented “psychohistory” and lays the foundation (sorry) for the later books. The revelation about the nature of some of the characters surprised me. Asimov was a master pulp craftsman and this was a fun read.
