Let me start by saying that Jeff Hays is an absolute genius! Okay now that is out of the way, the background music that was added to this book gets overpowering and at points makes it difficult to understand the narration. It was so bad in some spots I had to put on headphones to make out the reader from the noise. I get what you are trying to go for here, but this might be one of those too much of a good thing scenarios. I hope that sound booth reads the reviews. I would happily buy the next book and definitely look forward to hearing more exploits of my favorite murderous box.
