Prelude to Foundation

Written decades after the original trilogy, Prelude to Foundation offers a fascinating look at the genesis of Asimov's greatest idea. Unlike the "fix-up" nature of the early books, this is a cohesive novel that functions almost as a travelogue of Trantor, fleshing out the world-building of the Imperial capital in satisfying detail. It introduces a younger, more vulnerable Hari Seldon, transforming him from a distant historical icon into a flesh-and-blood protagonist. The narrative pace is brisk, driven by a chase structure, yet it retains the intellectual core of the series. It effectively sets the stage for the decline of the Empire by showing the cracks in the foundation of its greatest city.

Isaac Asimov (1920–1992) was a Russian-born American writer and professor of biochemistry. A member of the "Big Three" of science fiction (along with Heinlein and Clarke), he was a frequent author known for the Foundation series and the Robot series.
