Although some will complain this last in the series is slow paced compared to the first two books, I think it does a good job at pulling together a lot of huge story arcs, which happen when your characters live over two hundred years. That said, there is a lot of expository narrative to read, however, I found it very worth it. I’ve read Sci-Fi voraciously since 1964. To me, this series seems prophetic. Perhaps some of the science is a bit dated, being conceived and written in the 1990s. We know a lot more now about the dangers and challenges we may encounter in our efforts to expand our reach into our solar system. All that not withstanding, I believe we (humanity) will overcome those obstacles. Maybe we could even learn to live together more harmoniously and efficiently, as conceived here in this series. I believe in the power of human ingenuity and creativity. We have a chance to truly find our place in the universe before we destroy ourselves. This series outlines one way that could come to be.
