When you foretell the decline of a galactic empire, you don't make many friends. But Seldon manages to keep what he finds low key and sets into motion a series of events that will lessen, not stop, the ravages that are to come.A great sci-fi classic. One of the best from an all time master of the genre. When I was younger I tried to track down every book he ever wrote. Think I got all the Tales from the Black Widows, but am not sure.Any lover of Sci-fi will find this not only exciting, but intelectually stimimulating.
Positive
