Back to my Pratchett re-read, and this is the first "witches" book. It's great. It's not a Rincewind book, and to be honest, I think it's the better for it. Pratchett's started looking at the Discworld a bit more widely, and it begins to round out the world nicely. To me, this feels like the first proper Discworld novel, in the style of the later books. I think Granny Weatherwax and the witches generally are great characters, which is a definite plus, but even without that the style is showing the promise of the rest of the series.
