Please do not order my book from anyone promising to deliver it before September 14, 2017. Amazon and legitimate book stores should show the correct on-sale date. You're welcome to pre-order it, for delivery in September. In fact I encourage that!
Here's why: I had to start publicity well in advance of the "on sale date," as they call it in the book business. In order to do that, I had to upload the cover and the "book block" (the book's text, all typeset into pages) to IngramSpark, the company who will be printing and distributing it. But since the book block still needs editing (typos fixed, other things adjusted, some sentences reworded), I had to upload a preliminary version at this time.
When IngramSpark sent an image of the cover to Amazon, apparently that was picked up by other vendors who appear on the Amazon web page (the one that shows my book), promising to deliver the book right away! From what I know so far, these other vendors do not have access to the actual content of the book, even the preliminary version I uploaded.
I have no idea if they will charge your credit card and then not deliver the book for months after all. I am still looking into this with Amazon and I will post updates here as I learn of them.
Meanwhile, I'm proceeding to march in the Boston Pride Parade on Saturday, June 10th (tomorrow as I write this) and will be distributing flyers to promote my book there.
