I enjoyed this book a lot more than I had expected after the first few chapters. I am a little sensitive to viewpoints that paint religious persons as idiots and only those who think we came from tadpoles as smart. I was afraid this book was going that way, but as I gave it time to develop, I found that while indeed the author has characters that fit that mold, he had many other types as well, and in the end, the possibilities of greater understanding of the truth that leads to our many believe systems is given a lot of room to breath. Perhaps a little too much pot smoking, but many of those partaking had issues which at least balanced the idea there is no impact from smoking.
The reactions to a "first alien encounter" are greatly varied, and being set in a timeline that isn't too unfamiliar to today, allows for an easy transition into most of the plot. The later stages of the plot are very thought provoking and in some ways, even harken to ideas such as Stargate discussed. In the end, I enjoyed this and look forward to the next chapter in this saga.
