Loving this series! Not only are the books as a whole great, but the narrator in this lineup has taken the time to come up with amazing voices for every character, and some fairly non-intrusive special effects for the production. These are mostly voice modulations for the AI, not full on audio-play effects that can be distracting to some (though I’d definitely be interested in hearing a full audio play version of this).
Give the series a try, definitely worth it!
