Hari Seldon begins devoping his "psychohistory" theory in this prelude to the famous "Foundation" trilogy (which as grown to many more than 3 books).

Seldon ends up being pursued by a number of forces who would like to exploit his theory for their own benefit, taking our main character through a variety of societies. Asimov again works his magic with creating intriguing environments for his characters to play in.

Asimov had a number of logical twists at the end of the book; some that I saw coming, and some that I didn't. The main characters were a bit "invincible" for my tastes, but tension was maintained well.

I definitely look forward to continuing the series.
