I'm just utterly baffled. How on earth did buyers even find your book if all you did was list it for Kindle (and other e-book selling formats) and create a website?
I wrote a book on exercise and nutrition, somewhat specialist in nature but desirable for various reasons. I spent about £1500 on a website, hoping to sell the book using that. No luck at all, and all my efforts to advertise the website (posting on forums, google+, facebook) were useless. I listed the book on kindle, and if I'm lucky it earns me £10-15 per week.
Everyone who reads my book rates it very, very highly, but the fact remains that the internet is vast, the Amazon Kindle store is vast, so hardly anyone finds it. So again, I'm baffled, how on earth did over 10,000 people find your novel, never mind find it and buy it? How on earth does anyone find your website?
Note: however baffled I am, I'm also impressed! You must write very well.
Coragem.
