Back to the re-reads of Terry Pratchett. I've been very lax in writing this review. I think I must have read it a month ago, during treatment. Such is life.
It's peak Discworld Pratchett. The jokes are thick and fast, the plot is fun, it's... just really solidly put together. It comes across that opera (the subject of the book) is not really Terry's thing, but he takes inspiration from the passion of others, not entirely unlike Unseen Academicals dealing with football. And, as peak Pratchett, it does so effortlessly. I'd forgotten that a) it's a witches book (since it takes place in Ankh-Morpork), and b) how much I like the witches.
Weirdly, it's also something of a non-descript book. I'd forgotten so many details of it. Very little stands out per se. It's a little lost in the mid-cycle. Yet it's also very good. It doesn't have to be a unique masterpiece, it can just be consistent fun.
