Unfortunately, I have to say that so far this is my least favourite Discworld book. It was by no means a bad book, I just didn't click with it as well as I have with those before it.
I really enjoyed the book before they got to Genua. I thought the parodies on various fairytales were hilarious, and loved seeing the witches navigate new places.
However, once they got to Genua I really lost interest in the story, and I really didn't understand or care about the last 70 pages or so. I felt like I was missing important elements of the story, and I didn't really find anything funny.
For the most part I thought the satirical portrayal of casual racism was handled really well, especially for being written in the 90s. But there was one thing that was out of order, and that was one of the witches calling a servant a 'charlie chan'. From what I can tell this has been used in the past as a derogatory name for Asian people, which obviously I'm not a fan of. What makes it worse is that Discworld doesn't even have an Asia, so it doesn't even make any sense to use it?? Just unnecessary.
All in all, not an awful book by any means, but definitely my least favourite so far.
