Hurtled through time from 1949 Chicago to an Earth during the heyday of the first Galactic Empire, retired tailor Joseph Schwartz finds himself on a backwater, insignificant planet with much of its land ruined by radioactivity and so poor that its inhabitants are sentenced to death at the age of sixty--and Joseph is sixty-two--in a new edition of the author's first novel. 15,000 first printing.

High above the planet Florinia, the Squires of Sark live in unimaginable wealth and comfort.  Down in the eternal spring of the planet, however, the native Florinians labor ceaselessly to produce the precious kyrt that brings prosperity to their Sarkite masters. Rebellion is unthinkable and impossible. Not only do the Florinians no longer have a concept of freedom, any disruption of the vital kyrt trade would cause other planets to rise in protest, ultimately destabilizing trade and resulting in a galactic war. So the Trantorian Empire, whose grand plan is to unite all humanity in peace, prosperity, and freedom, has stood aside and allowed the oppression to continue. Living among the workers of Florinia, Rik is a man without a memory or a past.  He has been abducted and brainwashed. Barely able to speak or care for himself when he was found, Rik is widely regarded as a simpleton by the worker community where he lives.  But as his memories begin to return, Rik finds himself driven by a cryptic message he is determined to deliver:  Everyone on Florinia is doomed . . . the Currents of Space are bringing destruction. But if the planet is evacuated, the power of Sark will end--so some would finish the job and would kill the messenger. The fate of the Galaxy hangs in the balance.
