As somebody else commented above, there’s a very simple solution to your issues: re-reading.

As a rule, books you wouldn’t enjoy rereading at some point in the future aren’t worth the trouble the 1st time around.

Maybe change the kind of books you read.

And find ways to handle your obsessive need to know in advance and be always right. I’m no expert, but I’d wager you have the same problem in life outside of your reading.
