I'm a librarian who loves anime, manga, and reading a wide variety of genres.
I wouldn't be surprised if someone told me that Kobna Holdbrook-Smith, the narrator, was either a little sick or suffering from allergies during the recording of the first couple hours or so of this book. His ability to breathe and speak has improved*, though, and now I'm debating getting another audiobook in this series. The problem: I didn't really like the second book, Moon Over Soho, and I'm not sure whether I'd like my first time through Whispers Underground to be via audio.
* - It's not like the problem was ever that bad to begin with, but it was noticeable. I feel a bit weird about focusing on a narrator's breathing so much, but hey, I've rejected audiobooks because the narrator had a slight lisp, or emphasized words strangely, or any number of other nitpicky-feeling reasons. Breathing is part of the package too, I guess.
