So I'm thinking of reading something by Terry Pratchett, but he has so many books I'm unsure where to start. What is either a good place to begin or the book which is his best work?
The Discworld series is written in such a way that you can pick up any of them and have a reasonably good idea of what's going on, but they are chronological. So it'd be best to start with The Colour of Magic and The Light Fantastic. Or if you want a non-Discworld offering to start you off, there's Good Omens, the biblical apocalypse novel he wrote with Neil Gaiman. It's quite good because he keeps Gaiman's worst excesses in check and vice versa.
I shall keep all of those in mind. I recently turned on my KIndle and saw the first volume of Mark Twain's newly released autobiography, so I'll be spending time with that. But I'll definitely peruse through the Pratchett you kindly recommended and pick on.
I've never read Gaiman's novels, but I used to read "Sandman". I assume he's a bit overindulgent. I did however meet him when he gave a "Sandman" signing here in Salt Lake many years ago. At the time the comics illustrator, Mike Dringenberg, was living in the area so that might have persuaded him to come out here...
