Someone compared Pterry's ability to mould language to Shakespeare, if only I remember where I heard or read this comparison.

I have recency bias with The Colour of Magic, reread it fairly recently and it's quite brilliant, although the first 10-15 pages were difficult to get through because they were somehow opaque. So many characters I just met talking to each other and about each other, and it was often unclear to me who or what they were talking about. Then Twoflower arrived and saved it.
