The multiorgasmic man.
Chuck Palahniuk’s Haunted is the first thing which popped into my head.
It’s a ‘diegetic’ anthology, the context is reminiscent of Sartre’s No Exit in many ways, but taken to Palahniuk’s particular style of extreme.
There’s one short story in it which caused furor back in the day, but I honestly found the meta-context to be even more philosophically gruesome.
Edit: may be biased, I got the book as a gift from a girl I used to like a lot, but she… well, let’s just say she was living that book at the time.
I’m gonna try that! Not really a book, but guts by him is also grotesquely integuing.
In elementary school I read this book called “Flawed Dogs” and it was unforgettably wild. It’s about a dog who escapes some kinda confinement by jumping over a barbed wire fence and loses his back legs in the process, and then joins a dog gang and does dog gang activities. Also one of the dog gang members was a cat in disguise.
Honestly I should see if I can find a copy of it and reread it. It was pretty wild.
edit: I looked it up and maybe I have a lot of the details wrong but it’s still pretty wild
The one that included the most wildlife might be hard to know exactly, but ‘The Lost World’ by Arthur Conan Doyle might be a contender.
One of my favourite books, and one that gave me lots to think about was His Dark Materials by Phillip Pullman.
The most ‘different’ setting for a book that I’ve read might be The Planiverse by AKA Dewdney, which takes place in a 2d world with thought out and realistic physics and societies.
I’m not sure if it’s the wildest but the first that comes to mind is “John Dies at the End”
