This is an interesting little story by Murakami. But heads up for those who are already reading 1Q84: the story is literally pieced together (or the other way around) from that book. It describes Tengo's relationship with his father, and the trip he takes to the sanatorium. There's nothing in this story that doesn't appear in 1Q84. If you haven't read that however, I can recommend this short story as a standalone.
