Finally all three good links for Demons of the Past!

There was an ongoing problem with Amazon's listings of my space opera, Demons of the Past (Revelation, Revolution, Retribution), making the three of them have the same cover and confusing would-be purchasers. 

Finally it's straightened out, and here's the proper links:

#1, Revelation: https://www.amazon.com/Demons-Past-Revelation-Ryk-Spoor-ebook/dp/B0DN6Q6ZZ7
#2, Revolution: https://www.amazon.com/Demons-Past-Revolution-Ryk-Spoor-ebook/dp/B0DN6SVXF6
#3, Retribution: https://www.amazon.com/Demons-Past-Retribution-Ryk-Spoor-ebook/dp/B0DN6PL1ZT

This is the work I spent the most hours on over the years, rewriting it at least five times since its first draft in about 1982 or so (and the idea having been first thought of in the late 70s).
