Well, I completely wasted my time. I spent hours re-creating my book in Word so I can submit a PDF for a softcover version of the book, and I couldn't publish it anyway because Amazon requires a minimum of 72 pages, so it's a Kindle only book.
It's already been approved for sale, so here it is for anyone interested: https://www.amazon.com/dp/B0CKTZYDLM
@Mugnika probably not anytime soon. Since the book is so short, I'd like to collect some background ambiance and make the audiobook worth the minimum price.
