THE GAME-PLAYERS OF TITAN
From the Back covers

The creatures from Saturn's moon could appear human or inhuman, at will. And the elaborate contest they set up with the remnants of Earth's humanity was just as treacherous. For though the war had been fought to a stalemate, the unending series of gambles could upset that truce-and end the world. Philip K. Dick, author of EYE IN THE SKY and SOLAR LOTTERY, was the winner of this year's "Best Science Fiction Novel" award. We predict that his newest novel, THE GAME-PLAYERS OF TITAN, will be a leading contender for next year's Hugo!
