To be clear, it doesn't bother me if the authors themselves are liberals, as long as the book/story doesn't have woke nonsense. In that sense, I guess older novels would be the best bet.
EDIT - Holy moly, thanks for all of the suggestions. I have my work cut out for me, looking into all these authors this summer.
Not coincidental at all. Basically went straight to the library
Awesome, glad it hit home. It's a fascinating read.
