Foundation’s Edge

Amazon

At last, the costly and bitter war between the two Foundations
had come to an end. The scientists of the First Foundation had proved victorious; and now they retum to Hari Seldon’s long-established plan to build a new Empire that the Second Foundation is not destroyed after all — and that its
still — defiant survivors are preparing their revenge. Now the two exiled
citizens of the Foundation-a renegade Councilman and the doddering historian-set
out in search of the mythical planet Earth… and proof that the Second
Foundation still exists. Meanwhile someone — or something — outside of both
Foundations sees to be orchestrating events to suit its own ominous purpose.
Soon representatives of both the First and Second Foundations will find
themselves racing toward a mysterious world called Gaia and a final shocking
destiny at the very end of the universe!
