If I had to choose one word to describe this book, it would be "tedious." There are interesting ideas here, but they're buried in minutia. As a novella, I might have enjoyed it; as a novel, I was mostly just glad it was over and that I wouldn't have to read any more pages about how the characters ate, dressed, or shit.
Also, I will grant that Kafka is realistic as a fifteen-year-old boy, but that doesn't change the fact that his cock is much more interesting to him than it is to me.
My version was narrated by Steven Carpenter, who does a very nice job.
