I have to hand it to the goodreads recommendations engine, this was a really good one! It was recommended to me on the basis that I liked The End of Mr. Y, which is one of my absolute favourites.
And in terms of weirdness The Raw Shark Texts come up a close second.
I was hoping for a bit more of a [excuse me] mindf*ck here but all in all it was great. Anyone interested in the system and connectedness of language and ideas, of concepts and reality, and of coding and decoding should read this. Apart from these rather weird things, it has suspense and love and more weirdness.
So, thank you goodreads, for showing me once again why I have been a member here for so long and why I keep coming back (several times a day)!
