If that’s your concern, I’d like to add some context about Discworld.
Firstly, it’s not really just one series – it’s a group of books all set in the same world. Some sets of books follow the same group of characters, but there’s a few that are standalone. Monstrous Regiment is my favourite of these. Without spoiling it, it’s about a girl who joins a regiment of soldiers to find her brother, also missing in the war. While not a Discworld book, Good Omens was a collaboration between Pratchett and Neil Gaiman that’s a very fun book to read.
I’ll also give a rough characterisation of Pratchett’s writing. It’s built on using humour and a strong sense of right and wrong (which most people on Lemmy are broadly likely to agree with) to make a point, while also telling a compelling story.
TLDR: Monstrous Regiment good standalone Discworld, Pratchett funny with big heart.
