Preview of Haruki Murakami's new novel: a journey through the walls that build reality. That summer afternoon we went up the course of the river wrapped in the sweet aroma of the plants, we were avoiding timid dams.

The stream of water lapped at our ankles and our feet sank into the fine sand of the bottom as if into the soft clouds of a dream. Two birds crossed it, fast as arrows, tearing it with a screech. There we were surprised by the mute, bluish gloom of the sunset.
