I wouldn't read it, personally, for several reasons, but I did look for it after it was initially released. I never could find a digital copy, though sometimes those are delayed with self-pub releases. I haven't looked in awhile.
Honestly, I suspect he purchased the cheapest option available from the self-publisher, and those usually focus heavily on physical copies rather than digital copies, which would be easier for someone to promote and sell in the modern publishing industry (In my humble opinion, these options are the equivalent of a scam that take advantage of authors unaware of how the industry works, but that is another topic.)
In any event, I suspect it is hard to get a copy of it if it is only a print book.
