Give this one an 8/10. I didn't take to it first time I read it years ago but my sister-in-law got me back into reading Pratchett. The story starts to sag about 3/4 of the way through and some ideas aren't very well fleshed out and seem incomplete, but the ending is something else. It's one of his earlier Discworld books, so his style is a little different to the later books, but I really enjoyed it. Rincewind is a great character and Pratchett's wit is as razor sharp now as it was then.
