Although written in the same style as the forgettable The Currents of Space, this novel has a better story. A 62 year old retired tailor from 20th century Chicago is transported to a future earth so poor that citizens are euthanized at 60. His arrival and subsequent actions change the world. If you want to read Asimov (and you should), read the Robot books or Foundation instead.
Incidentally, this particular cover uses one of my favorite pieces of art of all time, by the late Peter Elson.
