Wow it must be pretty damn good.Legendsmith said:Foundation and Empire by Issac Asimov.
If you like science-fiction (real sci-fi, not science-fantasy like Star Wars) then you must read the Foundation series.
The Foundation Trilogy (the first 3 in the series) won a special Hugo Award for "Best All-Time Series" in 1965. It is the only series ever to have received this award.
(Note: Asimov himself assumed that the "Best All-Time Series" award was created to honour The Lord of the Rings, he was amazed when his own trilogy won).
