Folks– It took some doing, but I got a listing for Emperor Tom on Amazon! This includes the option of reading the book online via Kindle, or purchasing a print-on-demand version of the book. The Kindle version includes the Guided View feature, which I think is pretty cool! The print-on-demand book is a somewhat different format than the Mixam press run I did earlier this year, and a bit more expensive, unfortunately. But it was a good experience, and the listing is 100% free!
After the Kindle Select period expires in December, I will submit the book to Comixology; keeping my fingers crossed about that!
