    The unthinkable had happened, a major urban transit system had become the target of a terrorist attack. In an attempt to discover why, Haruki Murakami, internationally acclaimed author of The Wind-Up Bird Chronicle and arguably Japan’s most important contemporary novelist, talked to the people who lived through the catastrophe—from a Subway Authority employee with survivor guilt, to a fashion salesman with more venom for the media than for the perpetrators, to a young cult member who vehemently condemns the attack though he has not quit Aum. Through these and many other voices, Murakami exposes intriguing aspects of the Japanese psyche.
