@onepict Yes, I re-read Jingo, Fifth Elephant, and Night Watch because they're good but also because I hadn't read Snuff yet and wanted a run-up. My last ever "new" Discworld novel is (edit to correct title) Shepherd's Crown (/edit), so I was planning to re-read the earlier Tiffany Aching books beforehand and as Carpe Jugulum is the last Witches book pre-Aching I can add that too. I read a lot so an extra light novel here and there is easily achievable.
I didn't think Snuff was up to snuff, which is understandable under the circumstances, but I'm glad we were allowed to have it, and there are a few classic quotables. I don't remember much about Thud, but there's good stuff about politics (and rulers) all the way back through the Watch books.
