A Tumor at the End of the X-Ray

I Read Everything. I’m Deep in a Reading Slump, and I’ve Been Reading for Years. Any Genre Is Fine

I'm looking for books similar to "The End of Ten Days". I'd like something with good writing and a decent plot, but not too tragic. I've read pretty much everything on the high-rated lists, so I'm looking for the best of the best. Thanks, everyone. Finding one in this vast sea of books is really like searching for a needle in a haystack.
