Catch 22. I laughed out loud several times. An incredibly poignant look at war.

Naked Lunch by William S. Burroughs is to books what Eraserhead is to movies. An insane twisted mindf*ck.

I recently began Calvino's infamous "If on a Winter's Night a Traveler" which is the MOST experimental book I've ever read. So much so that I couldn't keep reading it. I will conquer it one day, but I just got annoyed after the first few story starts.

Another odd one I read years ago is by Lionel Shriver called The Post Birthday World. In the first chapter, a woman meets with a choice. The rest of the book alternates chapters, one where she did and one where she didn't. Then the last chapter is the same. Which took a lot of doing, because what happened when she did and didn't were wildly different. Also, he kept some things resonating between the two timelines. It's really clever.

Finally, okay I just realized you didn't say weird, but I'm onto weird now, so Ian McEwan. Just the weirdest shit ever. Love it! Mostly.

Slaughter House 5 by Kurt Vonnegut

Trump's presidency.

Well if we're going for possibly insane Valis by Philip K Dick

Anything by Octavia E. Butler.

"The Dark Tower" series, Stephen King.

The Books (not the film) {also as a six sided vinyl record collection.
Hitch Hikers Guide to the Universe and
Restaurant at the end of the Universe.

Iain Banks novels, The Culture series. Just insane. Fabulously written in a way that will blow your mind. Don't try to understand them, just go with the flow.

"Books! - are they still going? " - Homer Simpson

Neil Gaiman's Neverwhere, heck everything he ever wrote.

Against Nature by J.K. Huysmans.

Favorite AND insane? Definitely American Gods. Wildly imaginative.

Well,I like the disc world series by Terry Pratchett. It's highly entertaining fantasy. I really bust up when the character of "Death" tries to be more personable.

I am partial to anything written by Issac Asimov or HP Lovecraft. I believe I have read everything they have written. Both tell great stories.

Everything by Robert rankin but if I had to choose its between hollow choclate bunnys of the apocalypse or nostradamus ate my hamster

Hunter Thompson.
Kurt Vonnegut.
.....take your pick of their writing.

There are so many incredible works that I couldn’t possibly name just one, so I will list top 5: The Complete Works of Sir Arthur Conan Doyle (basically every Sherlock Holmes Story), Lord of the Rings Trilogy, H.G. Wells Collection (The Island of Dr. Moreau, The Time Machine, The Invisible Man, and The First Men in the Moon. My mother had a leather bound edition of this that I completely wore out as a kid), The Dark Tower Series, Watership Down (this is total nostalgia as I read this over and over as a young kid).

I had a roommate that briefly went Mormon. Their book is just delightlfully funny! The infallible diety finally noticed he made a few mistakes, and told ONLY ME how to fix it, so follow my path.

He only stayed a few months, Was actually only using them to try and help witn his alcoholism. The Mormons drove him back to the bars
