The Hitchhiker’s Guide, you likely won’t be able to finish each of the 5 books in the trilogy in a day but it’s something you can read a hundred times and find a new witty joke somewhere, much like all the Discworld novels.

The Expanse is another that you could burn through a book a day but wow it’s a hell of a story and worth taking your time on each character’s perspective, Outlander is also a good one for the same reasons but those are 1k pagers
