This book was written in the '80s so some of the things that happened wouldn't have happened with today's technology and science, so that had to be taken into account. It was pretty slow going until about the third chapter from the end, then things started happening fairly quickly. It was interesting, but not un-put-down-able. If you like books written more than 20 years ago, this is a good one. It's clean, with some mystery, some romance and full of wholesomeness.
