I enjoyed several of the Xanth series, but after a while there is a sameness. And a odd story - My dad and a friend went to hear Piers Anthony speak in Seattle years ago - they were so appalled by his talk that they simply set aside his books. I don't remember if it was sexist or racist or just potty-mouth - and they are both quite liberally minded consumers of fiction and give the author a lot of latitude - but they were NOT impressed by the man in person. I don't think such a thing can be said about Pratchett.
