I just finished rereading Lonesome Dove, again. Don't let the western theme fool you. It's quite possibly one of the best novels ever written. Every word, every character, every like of dialogue is crafted to perfection. It will leave you with a book hangover like nothing else.
I came across it from a post/comments on Twitter and people were proposing that a character from the book resembles one of our current Billionaires who does car, space, social media things among others.
