SF. Ace Double- Jane Roberts"The Rebellers" / John Brunner "Listen! The Stars"

Listen! The Stars - John Brunner.

Called a stardropper, a simple device made from an amplifier, a magnet, a vacuum, a power source and an earpiece.  Add it up and you get nonsense - in the form of strange sounds, unintelligible to the human race.  But was it "nonsense" that drove people mad, creating an addiction similar to dope?  Was it " nonsense" that caused people to disappear off the face of the earth without a trace?   Stardropper - a menace to an insne world, or a warning from the stars?

THe Rebellers - Jane Roberts.

In the 20th Century, a typical, quiet, small American city - in the 23rd Century a teeming, wildly overpopulated "contropolis" where millions of starved, half-crazed people swarmed through the streets in a purposeless search for food, rest, or for death. Above hte mad carnival-like scene the loudspeakers blared out their command to work, until night brings quiet and the "streetcleaners" come to shovel up the bodies of the dying.  Into this nightmarish world came Gary Fitch, a man who had not seen the outside world for fifteen years.

A 1963 Ace paperback in good condition based on the Hancer Standard.
