So, as it turns out, it is common for a book that is listed on Amazon.com to be made available before the cover art is posted. I just have to wait. Just like I have to wait six weeks for an iPad version and a Kindle version to be ready.
I am not so good at waiting.
And I would like to take a moment and beg you to please buy the book if you are finding this information helpful at all because I will have to get a real job if I don't sell some more copies.
