Having read the first two parts and enjoyed them I then finished by reading Book 3. It's a bit longer and reflects the fact that the author's son and daughter are older. It was originally written for them, and their namesakes are the main characters in this SciFi adventure. There's alien technology beyond human understanding in the story, but human science is accurately portrayed and described. Like other books by the same author, I found it to be an easy-to-read page turner.
