I came across the general story from reading an excellent newspaper article by Egbert for the Mercury News after the hike. I wish I could find it to post here, but at least for the time being will have to simply say that it was a really good piece and I enjoyed it more than the full-length book itself. While the topic of the through hike for a family that included the youngest person to ever hike the entire distance was interesting, I wasn't a huge fan of the narrative structure of the book that had chapters organized as topics rather than narrative following the duration of the hike.
This said, it was an interesting story and I have to give huge credit to both the then 10 year old daughter who completed the journey and the parents who did it along with her. Further details about the Egbert family can be found on their website, PCT Family.
