Then The Sky Split Open. One moment Kenniston was strolling down the quiet street, lost in pleasant reverie The next moment the sky plit open! It split wide open, and above them was a burn and a blaze of light - so swift, so violent, that the air itself seemed to have burst into flame. Then there was silence - awful, suffocating silence. Kenniston felt the chill of premonition - a shapless terror that grew into a thing too evil to be borne alone. This novel describes the shocking experience of a group of ordinary people, catapulted by a mysterious explosion into the terrifyingly strange world of a million years hence. It is not a prophecy - but a warning!
