This is a very compelling piece of modern noir narrated by a young Japanese man who guides tourists through the Tokyo sex districts. He acquires a most unusual client, an American, and from their first encounter, he senses that something is not quite right. 
 I waffled between 3 and 4 stars for this one. I've edged it closer to 4 stars, because Murakami sets the mood so well and it was so compelling that I read it in two sittings. It has some violence that will not sit well with the easily squicked, though those familiar with Murakami's other works might consider it mild. (I've not read his other books, but I did see the film Audition. *shudder*)
