Some of the Discworld novels fill the "satire, political commentary" criteria. I'd recommend the Moist books (Going Postal and Making Money).
Now, to the mindscrew department. There is Zoo by Otsuichi, but I'm afraid it's not available on Kindle.
Oh, oh, there's also The Posthumous Memoirs of Bras Cubas by Machado de Assis, which is a Brazilian classic about a man who dies and exposes his pessimistic views about society to the reader in his own afterlife. And if you want another one of this author's notable works, try Dom Casmurro, which is about an Unreliable Narrator exposing his past.
I've read all of the discworld books, my favourite series of books by far! The other suggestions look quite good, but I was thinking something along the lines of neal stephenson or aldous huxley or gravity's rainbow or the illuminatus! trilogy or something? (lots of 'or's...)
Danger's over, Banana Breakfast is saved. FC: 0576 - 4632 - 1517I always recommend The Vorkosigan Series books for anyone who like sci fi.
SPATULA, Supporters of Page Altering To Urgently Lead to Amelioration (supports not going through TRS for tweaks and minor improvements.)Have you read Gene Wolfe's Book of The New Sun? Definitely one of my favorite pieces of speculative fiction. I'd also recommend read The Metamorphosis of Prime Intellect. Of course I'm excluding Phillip K. Dick and J.G. Ballard as you say you've read the usual classics.
Journalism is just a gun. It's only got one bullet in it, but if you aim right, that's all you need.

Hey guys, Desparately need some book recommendations, kindle versions only, as I have a long journey tomorrow with no respite in view. I enjoy po-mo, mindscrew, satire, political commentary, sci-fi and speculative fiction but have already read the usual classics... Help!
