Lights Beyond the Stars 1

I got this from a free indie scifi BookFunnel link and signed up for the author's newsletter! I love the concept of this as they are labeled as a mini-trilogy, while all together they're around a novellas length. I would love to continue, but they only show as being on kindle unlimited, with no purchasing option. 
Dario is an archeology student that has a leaning towards ancient architecture...ancient alien architecture. Since seeing a flying saucer as a child, he's thought of little else, but he wants to put actual facts and study towards proving it. 
The author writes an enticing opening in only 33 pages. The character has depth and personality, and even a nemesis. The facts, although not deeply gone into, read as researched and real, and I enjoyed the idea of a scifi story that simply reads as real life. 
If you know a way to get the others, let me know!
