I struggled with this at the beginning but the ending really pulled it together for me.
I looked at the book as I listened to this audiobook. I enjoyed the sound effects that were added to the audio to get across some of the things happening in the pictures. I'm disappointed that extra details were added to the audio that the reader couldn't have figured out on their own if all they were doing was reading the book. The scene at the school dance is one example.
