Reading Haruki Murakami is, for me, a lot like watching a David Lynch film: I'm never really sure what's going on, and I spend most of it asking what the hell is happening, but I sure enjoy it.
Kafka on the Shore is no exception. It's beautiful, mysterious, and probably a very good metaphor for something, but I don't know what that is. Nonetheless, it's a good read. Get after it.
