Dreams by Derrick Jensen. It’s the only book to have that kind of sudden dramatic effect on me.
Tbh the author is legitimately insane. He believes he has muses on the ‘other side’ telling him what to write and what not. The bulk of the book is basically him explaining why he believes that. The main story isn’t what affected me though.
He’s also a pretty hard core environmentalist. He advocates for blowing up damns and such(crazy). Which I can’t really get behind but he also just talks about the state of the environment. And the way he was able to describe the current distress of the natural environment shook me to my core. That was almost ten years ago now and I still haven’t recovered.
Ismael by Daniel Quinn, I’d just be happy if they’d read it.
