To avoid this constant volatility, I raised the price to 2.99 - a price that had been pretty stable in the past. To my chagrin, the book is listed at 3.80 now.
Whatever. I give up. Amazon will list the book for whatever it damn well wants regardless of what I do or don't do.
If anyone out there is interested in reading The City of Earthly Desire as an ebook, simply contact me and I will happily send you a copy of the novel as a PDF or epub via email in exchange for some feedback, a share, or a review.
