The Currents of Space, Isaac Asimov - read online - Book Universe

The second book in the Galactic Empire series, the spectacular precursor to the classic Foundation series, by one of history’s most influential writers of science fiction, Isaac Asimov

Trantor had extended its rule over half the Galaxy, but the other half defied its authority, defending their corrupt fiefdoms with violence and repression. On the planet Florina, the natives labored as slaves for their arrogant masters on nearby Sark. But now both worlds were hurtling toward a cataclysmic doom, and only one man knew the truth–a slave unaware of the secret knowledge locked inside his own brain.
