Fanchon's Book was published in 1972 by Venus Library, a U.S. publishing house originally specializing in re-prints of vintage pornography, in particular American clandestine erotica from the 1920s and 1930s, that also published contemporary S/M stories. There is actually a very interesting story behind Venus Library - you can read more about it here. Fanchon's Book is apparently one of its finer releases. I was unable to find anything else by "Zane Pella", but the book's copyright is held by Gilbert Fox, who wrote a number of soft-porn books throughout the 1960s under pseudonyms Dallas Mayo and Kimberly Kemp.
