This was ok. I've decided to read all the novels in the Austin family series because I loved A Ring of Endless Light so much as a teenager. I would have liked this better as a teenager too, but now I just rolled my eyes through a lot of it. Zachary was SO unappealing and the writing wasn't great. I really want to travel across the US with the kids some day, so I thought I might like that aspect of it, but no, that was just the backdrop for the rest of the story. Not really worth reading, except to get more background on the characters in A Ring of Endless Light.
