In Prelude to Foundation, Hari Seldon is a young mathematician who’s just given his first paper on psychohistory, to popular acclaim. He immediately discovers that giving it was a huge mistake. Now forces far beyond his control are jostling with each other for control of the predictive and persuasive power of psychohistory. Seldon is forced into flight, in the company of a history professor named Dors, a flight that takes him to some of the weirdest sectors of Trantor, the capital world of the Empire.

I wasn’t sure if Asimov meant for this book to be read last – it was recommended to me that it come last. Some of the “mysteries” in the book weren’t mysteries because of clues/answers dropped in other books. There isn’t all that much on psychohistory in it, either, although it certainly shows how Seldon was set on the path to psychohistory. It’s more interesting than Forward the Foundation, and there are links to the Robot series, which I now have to read, darn it!
