Great job of narration. Jeff Hays but a lot of effort and time in this narration and it shows. For example whenever there is a part with a microphone you actually here it as if he is using a microphone. Not many other narrators would do that. I also like that internal mobile (thoughts) have a distinct sound that slightly echoes. I could also name a few others but you get my point. He is an awesome narrator. Loved the book as well. Hope he continues with this series since he really brings it to life.
