I'm looking for books to read, since I have more free time than I used to and I want something to do that I don't feel weird mentioning to my family when they ask what I'm doing to keep busy. Ideally fiction or relatively non-serious nonfiction, so this isn't a request for theory, though I might read it if you recommend it. I'm cool with whatever genre wise, but at least give a brief description. Ideally I should be able to get it at my local library, but if it's too obscure for that I'm fine with using other methods.
Have you read any Terry Pratchett? They're light but smart and very well-written, and there's a million of them. Pretty likely your library would have them too. Maybe skip the first couple where he was still finding his feet, Mort or Small Gods might be good ones to start with.
Guards! Guards! is also a good starting point if you don't mind the main characters being cops. I also liked Going Postal or Monstrous Regiment as starting points
