I’m a massive Discworld fan and find that the first few books (which are great) are not up the same standard of the rest of them. You are in for a treat!
I’m currently doing a cycle of books. I’m alternating between re-reading the (Queen of Science Fiction) Anne McCaffrey Dragonriders of Pern series (for the umpteenth time), re-reading Discworld series (even more times) and the Dexter books (first time).
For my non-fiction I have a data protection practitioners text and “The Rule of Law” by the late great Tom Bingham.
Incidentally, the Wyrmberg in Colour of Magic is a deliberate pisstake of Anne McCaffrey’s Pern stories
