My imperfect memory tells me that the first grown-up book I read and enjoyed was “2010: Odyssey Two,” the sequel to the far more famous “2001: A Space Odyssey,” both written by Arthur C. Clarke.
I wasn’t seeking “2010” when I happened upon the book in the LaPorte High School library. Maybe I was looking for a book-report subject. I don’t know. But I ended up loving that book. Still, for some reason, 20 years or so passed and I still never read any Isaac Asimov.
