I've never read any of Terry Pratchett's books, but it definitely does sound challenging to fully develop characters when there are multiple ones and the main focus of the books are different parallels. This is a great review and it has inspired me to pick up this series - thanks for sharing with the community, @steevc! Looking forward to reading future posts.
