The Goat Without Horns — Thomas Burnett Swann

"The Goat Without Horns" was Thomas Burnett Swann's first book-length work -- a strange tale of a remote island, an island which should be a paradise, but quickly becomes a nightmare in which all known rules of behaviour seem reversed. There, a young man brought up amidst the proprieties of Victorian England finds that his only friend is one small, lonely dolphin...and his enemies include several well-ordered hammerhead sharks...
