This is a Sequel to the Foundation Series. Some people from the Foundation find out that, according to their knowledge, there has to be a point of origin for humanity. A planet, somewhere in the galaxy, from where all humans came from, before they spread throughout the whole galaxy. And so they embark on an adventure to find that place, our Earth.
The whole Foundation Series is simply awesome. 7 books in total, they are all worth it. And all the rest of Asimov is worth it too. Especially the Robot Series.
