Agreeing with Jaguar again
(I must be feeling ill. it's the stress of the upcoming surgery.)
Terry Pratchett is easily the funniest, most consistently entertaining writer I have encountered. (and he doesn't seem to fall into the fits of depression that kept Douglas Adams from writing more, although I do love every bit of Hitchhiker's Guide, et. al. ... the BBC TV series is available on DVD incidentally)
It says a lot when the later books in the series fail to suck wind. (Piers Anthony for example ... good out of the gate, falls flat by book 3, doesn't give a damn but has to finish out the sequence ...)
I've got a good sized Pratchett backlog ... I have the books, just haven't made it to the top of the reading pile. I keep going back and forth on who the most favored character is ... DEATH, certainly, and The Librarian (ook).
