The truth is... these books are not easy to sell at first. You do have a good group of us here who share an interest in your creation (Game, book, story, etc) but it will still take time to get sales going.
I am sure you have information and second hand stories of other people who have done books so I will not write my own second hand tale...but know that its not a big sell right out of the gate.
Will I get the book? Perhaps. The economy blows... Family and Work must come first... Inheritance Cycle book 4 came out just before Christmas... Skyrim is draining our player base energy and time...
Lastly... Until I saw today's message... I thought you had started April fools day early.
One more thing. Remember that books are art. Continue to promote it but do not judge your work based on sales.
