On the non fiction front one that comes to mind is
The economics anti textbook (hill and myatt).
Though this was 12 years ago, public discussion of economics has progressed a little bit since, so it may not have quite the same paradigm busting feeling it did for me back then, but it's still pretty good.
Other mind expanding non fiction...
Feynman lectures (all 3 volumes)
Design patterns (don't hate me lol. Obviously less revelatory if you've already absorbed the knowledge by other means. And for flip's sake don't overdo them! )
