Mother Night, Slaughterhouse Five - Kurt Vonnegut

Stranger in a Strange Land - Robert Heinlein (it does have some anti-lbgtq messaging, but if I recall correctly it’s a single paragraph and Heinlein has known biases. The term “grok” came from this book; I’m not the only one who despises how it’s been co-opted by Musk)

Makes Me Wanna Holler - Nathan McCall

The Emperor’s New Mind - Roger Penrose (especially pertinent with the hype/propaganda coming from oligarchs surrounding AGI/ASI/the singularity)

The Demon Haunted World - Carl Sagan
