[Geoluhread]

I have never read anything that made me nauseated. Ever.

I read some sick shit though, I wasn't scared but I was amazed by the creativity of the author mainly.
The sickest thing I've read was In the Miso Soup. Oh man, half way through the book where the main .. ehm .. "event" takes place, I didn't think much of the book, but then it hit me. This book is awesome.

Another book gave me strange disconnected-from-reality feelings (although the content itself was very ordinary and not at all sick, mostly) was a book by Haruki Murakami called The Wind-up Bird Chronicle.
