Also, there is a new e-book version on Kindle-Amazon matching the print copy. The print copy is 91 pages, and Kindle e-pub is 143 pages in length.
Please be aware the edition being sold by Smashwords and other vendors is not the same as the current Kindle and CreateSpace print versions. My understanding they all should be the same. There are a few necessary requirements to fulfill at Smashwords. Before the end of April 2016, the copies sold wherever would be identical. The print edition should be on sale on Kindle/Amazon Prime in a few days before the end of this week.
