Edge of Time
by Donald A. Wollheim (as David Grinnell)
When Warren Alton went off to a quiet rural district of upper New York State to investigate some strange news reports, he figured it would be just a new type of "flying saucer" scare-only this time people were seeing dinosaurs and flying lizards!But what that star reporter uncovered turned out to be more fantastic than prehistoric monsters and more incredible than UFOs. For he found himself on a newsbeat that covered dozens of hitherto undiscovered planets, millions of miles of interstellar space, and thousands of years of time-and yet never took him outside the bounds of present-day America!
