SECOND FOUNDATION
by Isaac Asimov
Foundation (1951) and Foundation and Empire (1952) are the predecessors of this tale of galaxy security based on conflicting searches for the Second Foundation, established and hidden by the master psycho-historian, Hari Seldon. The Mule, wrecker of part of Seldon's plan, and members of the First Foundation are at odds; the Mule is disposed of and the First Foundation believes itself the victor. But the Second Foundation carries on, devising impromptu methods to maintain its superiority. The blue yonder, and not so wild.
