The Carnelian Cube, by L. Sprague de Camp and Fletcher Pratt, paperback fantasy novel
“Arthur Cleveland Finch was an eminently practical man. Naturally he didn’t believe that the carnelian cube was a “dream-stone” with supernatural powers. But, of course, if he were going to wish himself into another world, he would choose one where everything was perfectly rational.
Finch got his wish – with a bang! And he soon discovered that one man’s rationality can easily be another man’s nightmare. He awoke a poet in a strange place where status meant everything and a man could be tried for umpteen kinds of crimes for reciting a poem in public.
So, being optimistic as well as practical, Finch tried again – and again. And the worlds kept getting wilder, more improbable, and funnier – but more dangerous, too. The question was, could Finch find Utopia before losing his skin?”
