This one was quite interesting and much different then things I normally read. Science fiction is not my normal go to. Yet, I was so grateful that all three books were included in this one because after each one I need to know what happened next...and then next...and then eventually what was going to happen at the very end! The concept of the book was really neat and one of the reasons that I was so intrigued about what was happening, what was going to happen and eventually what did happen.
The basic concept of why are they are where they are, who are they really, who placed them there and what is bigger than them is a very spiritual concept. The way it is woven into the deep sea is fascinating.
