THE LOST PERCEPTION by Daniel F. Galouye                          Corgi Books. First Paperback Printing in English, 1968              Conditon: Very Good Minus                                                                                                                                                                 A science fiction novel by an American author whose books were more popular in Europe & the U.K. than in his own country.  This scarce edition precedes the 1st U.S. printing, which is known as A SCOURGE OF SCREAMERS.   A front cover crease, which lightly affects the first 60 pages; modest spine wear, including a reading crease, and browned pages.  But the book is firmly bound and has no markings.
