It's quite a while now since Renaissance e-books "published" my fantasy novel Goblin Mire and so far it has earned zilch. Whether this is because it's a crap novel or because it has never been promoted enough, I don't know. It is available quite widely, including on Amazon and Barnes & Noble, and on Renaissance e-books' own site, but without much success.
This makes me wonder whether e-books are any kind of answer, certainly without the backup of a printed version as well.
Or is it simply because I have been too lazy in promoting the book and have left it all to the publisher?
