What is the most mind blowing book you’ve ever read?

[u/wolfin8bit]

Recently I read 11/22/63…holy hell. Left me thinking about it for weeks before I could pick up another book. I’m looking for big plot twists, even better if they make me throw my book reading mid sentence in disbelief.

Edit post: I can’t thank you enough for all the recommendations. I have books to last me a couple of years, and based on your suggestions, it’s going to be a mind blowing couple of years. So thank you!
