Asimov's classic original trilogy comes to a close in this ambitious finale. Here Asimov has really gone over the top with political and intellectual intrigue, which propels the two main plot elements. As with the two previous Foundation novels, there are actually two shorter stories here that take place decades apart. In this installment Hari Seldon's plan gets back on track after being disrupted by the mutant known as the Mule, with the mythical Second Foundation starting to peek out from behind the scenes. Who works for whom, who's a traitor or not, and whether or not the Second Foundation even really exists are all intricately played out by a series of intelligent and conspiratorial characters in relentlessly tangled webs of intrigue. In fact, this book has the most well-defined characters yet to appear in the Foundation series, especially the young Arcadia. The original Foundation saga is wrapped up nicely here as the original trilogy comes to a close. Of course, Asimov's creation is so expansive that there was plenty of room for more speculation and development of the story, leading to the prequels and sequels that Asimov continued to crank out for this classic series.
