My answer: I hope so, yes!
Currently there aren't any specific plans for the first six books to come out in audio. We have a variety of thoughts and ideas on that subject bouncing around at Rooglewood Press, and my agent has looked into various audiobook companies as well. I do believe audiobooks of the novels will happen at some point.
It's going to be gorgeous, and I am so excited to launch into the audiobook world with this project!
Are you readers all audiobook enthusiasts? Back when I was pursuing my artistic career, I used to listen to audiobooks while painting portraits. I listened to the first three of the Series of Unfortunate Events as narrated by Tim Curry while portrait-painting, and they were delightfully depressing. Rohan and I will often grab audiobooks for long car rides too. We listened to the audiobook recording of The Graveyard Book while on an road-trip, and I think I loved it even more than the book itself (which I had purchased in hardbound as soon as it released)! The other audiobook I most enjoyed was The Spook's Apprentice: Curse of the Bane, which was, as the title suggests, frightfully spooky! An excellent audio-recording.
