I really love this book, but have to say that I never actually try to delve too deeply into the meaning or characters. To me, Hemingway’s prose is at its best in this novel, and I really just like being along for the ride, traveling from bars to rivers to bullfights with a bunch of people I’m not sure I really like, but they’re great to have on vacation.
Edit - a word
The Cannibalism book sounds interesting to me! I just put myself on the wait list for a kindle version from my library. There are dozens of us!
