Yes, Hard Boiled is my favourite.
I also like Norwegian Wood; though arguably it’s the least surreal of them all. I think the opening of Wind-up Bird is the best opening for a novel I’ve ever read. How does Murakami take something so simple, and use such simple language to such great effect?
I find the later Murakami books not as good as his earlier ones. I actually got a bit bored by Kafka and I hear the that the massive IQ84 trilogy has a strong beginning, but it dribbles out by book 2. (English speakers, you’ll have to find out when the translation becomes available..)
