I have been listening to your Imp series in audio (and I'd like to add that Angela Rysk is the perfect voice of Sam) and I love them! Will any of the Imp World books be made into audio? I don't have a lot of free time to sit and read a book, but I have lots of opportunities to listen to audio.
Demons of Desire is in the quality check process through Audible now and will probably be available in another week. I plan to have Sins of the Flesh done this year as well as the latest Sam book, Kingdom of Lies. The other Imp World books will probably be later next year before they are in audio.
