Totally came here to say Kafka On The Shore but I’m giving you a big ol’ head nod for this.

Kafka On The Shore by Haruki Murakami.

All of his books are a little odd but this one is truly baffling. Compelling story told using beautiful language and I kinda love it but I don’t understand it at all. I spent a few years post-read encouraging others in my circle to read it as well so we could “WTF?!?” at each other about it.
