The book was very imaginatively written and gave a good description of alien life in a parallel dimension. The beginning of the book did drag a little as the author spent a little too much time on the minutiae of daily alien existence before getting to the meat of the story. The description of the alien's technology and their ability to project their inner power (yar) to sense and control the world around them is fascinating. Also fascinating was the description of this world we live in from an Alien's perspective. There are a lot of spiritual and progressive concepts in this book as well as enlightened ideas about how we should treat each other and treat the world we live in.
