This was a full-cast audio production of a graphic novel I reviewed positively back in February. Noelle Stevenson is of Lumberjanes fame - a graphic novel I did not like at all. Nimona is altogether different, but I'm not going into any detail here since you can read that in my previous review. here's I'll just comment on the differences between it and the audio.
I wanted to listen to this because it struck me as odd that there should be an audio version of a novel written in a format that is known primarily for appealing to the visual! At first, I was annoyed. This audiobook succumbs to one of my pet peeves about audiobooks, which is that there is music. There are also sound effects. After a while I learned to tolerate all of this, but I was never completely happy with it. Full-cast is listed on the audio itself, but not on the cover, which mentions only three people: Rebecca Soler, Jonathan Davis, and Marc Thompson. They did do a good job, though, once I had got used to the voices.
Soler - who could actually play Nimona very effectively if the story ever got made into a movie - truly gets into her character and does a great job, and the other two, one of whom, I assume, does Ballister Blackheart, and the other Ambrosius Goldenloin, deliver beautifully. I recommend this version - it's very short, of course, but if you want some delicious villainy and intrigue delivered direct to your ear, then this is a great way to get it.
