Second Foundation

The Seldon Plan lies in ruins. A single extraordinary conqueror has done what statistics said no individual could, and the survivors of the First Foundation cling to one hope: the fabled Second Foundation, the secret society of mind-scientists Hari Seldon is said to have planted "at the other end of the galaxy" to safeguard his design.

In the first half, the conqueror himself hunts for that hidden order, certain it is the last thing standing between him and total dominion. In the second, a rebuilt First Foundation turns on the legend too, uneasy at the idea of unseen minds steering its fate, and a sharp, willful girl named Arkady Darell is swept into the search. The question driving both hunts is the same: where, and what, is the Second Foundation, and who is really guiding history?

Second Foundation closes Asimov's original trilogy on a series of reversals about knowledge, power, and who gets to hold the map of the future.
