Doorways in the Sand

The most playful - and arguably most accessible - novel by the master of inventive SF.Humanity
is not alone in the cosmos. The aliens have given a precious relic to
the people of Earth: star-stone. But the harmony of the galaxy is
endangered when they discover that the star-stone has disappeared.Likeable Fred Cassidy
is an eternal undergraduate. All he thinks he knows about the
star-stone is that it came to Earth in an interplanetary trade for the
Mona Lisa and the British Crown jewels. When Fred is accused of stealing
the cosmic artefact, he is pursued from Australia to Greenwich Village
and beyond, by telepathic psychologists, extra-terrestrial hoodlums and
galactic police in disguise. Follow Fred on his adventures as
he enters multiple realities, flipping in and out of alien perspectives,
through doorways in the sand.“Ingenious.”  The New York Times “That rarest of creatures in science fiction, the original character, emerges in Roger Zelazny’s Doorways in the Sand.”  Chicago Daily News “One of the highest tributes I have ever heard paid to a writer lies in the words of a young lady who said, ‘I knew, halfway through the second paragraph, that I was in good hands.’ Science fiction has produced many such hands, and I genuinely envy those who encounter Roger Zelazny.” Theodore Sturgeon, The New York Times Book Review
