That happens a lot with Transworld Digital. This book
http://www.amazon.com/Pawn-Of-Prophe.../dp/B0038AUYN2 which you can find by Googling has a kindle version that you can even "Look Inside" but says not currently available for purchase. It's rather confusing. Why list it if it is not for sale? If you go directly to Amazon (US) and search for it it it isn't listed at all in kindle books.
