I have been trying to wait for the audiobook for Elf Mastery to become available on Audible before posting this, but it's taking ages so I'm going to post some other links where you can buy it and I will add the Audible link when it becomes available. There may be other places you can get it (such as a couple online libraries) but these are the sites where I have seen it for sale:
Apple Books: https://books.apple.com/us/audiobook/elf-mastery/id1512945328?mt=11
Google Play: https://play.google.com/store/audiobooks/details/Bryant_Reil_Elf_Mastery?id=AQAAAEDsckkytM
Also if you do buy please don't be shy to leave reviews and ratings on Goodreads as well as the site on which you bought it! Some sites allow for separate reviews for author and narrator as well - if you have something nice to say about the narration I will pass it along!
Bryant Reil currently resides in Kelowna, BC. Recent accomplishments include completing a Master's degree, and having finished two books, Elf Mastery and Elf Doubt. The third book, Elf Righteous, is underway.
