Then there are the standalone Asimov science fiction stories that haven't been worked in any way into the Foundation continuity, chiefly The Gods Themselves and the Lucky Starr books (although the latter do mention the three laws of robotics and has off-Earth colonies that are hostile to the their mother planet). Foundation and Earth (Foundation sequel).Foundation and Empire (Foundation trilogy).Forward the Foundation (Foundation prequel).Prelude to Foundation (Foundation prequel).Pebble in the Sky (Standalone Galactic Empire book).The Currents of Space (Standalone Galactic Empire book).The Stars Like Dust (Standalone Galactic Empire book).Nemesis (Standalone book for the most part, but briefly mentioned in Forward the Foundation).Susan Calvin Robot short stories (collected for the most in I Robot).A rough timeline would be something like this: The novel is loosely related to the future history of his Robot Series, Empire Series, and Foundation Series, into which Asimov attempted to integrate his science fiction output. One of his later science fiction novels, it was published in 1989, three years before his death. Nemesis has also been retconned into the main continuity. Nemesis is a science fiction novel by American writer Isaac Asimov. Though chronologically the Empire books do fit in nicely between Robots and Foundation. So apart from the Robots quadrilogy ( Caves of Steel, Naked Sun, Robots of Dawn and Robots and Empire) and the Foundation series (original trilogy, two sequels, and two prequels) which should be read in order, there is little in the way of spoilers. Apart from the Foundation and Robot series, Asimov's works aren't interrelated very strongly.
