This may sound cheesy, but I would set up an affiliate account on Amazon, then you can post it using their ad display that has a more appealing approach. I do this for many of the Video Of The Day presentations I do so that you get thumbnails like the ones below the video on the link below: http://www.musiceternal.com/Video-Of-The-Day/2015/Sing-by-Blutengel-20150822 I would also check to make sure it is visible on all the Amazon sites. Amazon actually has more than one site depending on where in the world you are located. It was also mentioned above, but I would send free copies to people that are willing to review it for you and have them also post a link to the ebook (ideally like the thumbnails I mentioned above). This will show the book in the perception of the reviewer and have a nice means of directing the traffic to your book.
Hi, I requested a free sample of your crime book to download on my PC Kindle. You still need a couple of corrections in your Amazon description.
