Originally serialized in 'Analog Science Fiction / Science Fact' June, July & August 1975:- Synopsis: Man is no longer alone in the cosmos. The aliens have given a precious relic to the people of earth, the star-stone, but when it vanishes, the harmony of the galaxy is threatened. Fred Cassidy is a perpetual student cruising his way smoothly through life and human knowledge. All he thinks he knows about the star-stone is that it came to Earth in an interplanetary cultural exchange for the Mona Lisa and the Crown Jewels. But other sentient beings seem to think otherwise. Accused of stealing the stone, he is pursued by telepathic psychologists, extraterrestrial hoodlums, and galactic police in bizarre disguise. He flees into multiple realities, flipping in and out of alien perspectives, through doorways in the sand:- (original cost £0.75). [Lincolnshire, United Kingdom] [Publication Year: 1978]
