NOTE: This is about novellas, short stories and other ebooks that do not sell. It is not about the Zombie novellas as a genre!
OK, lets say your novella or short story sold a few copies then went into rapid decline like This One did. Now, two years on, instead of giving you that small but consistent income you were hoping for, it has dropped to a sales rank so high it resembles the number of dollars you were dreaming of making when you started writing.
What should you do?
