In book four Jed learned something important about the Transport's battle plans and intent on colonizing New Pennsylvania which I thought might have been the big reveal that explained why Jed was so important to the Tracer's mission. It turns out, the reveal in book four was only part of it and book five expands on Jed's role and answers all of the mysteries surrounding New Pennsylvania's existence, how the colony came to be and where it's actually located. I was pleased that those main questions that were bugging me were tied up in this book. I also enjoyed learning more about the Amish culture in this book from barn raisings to what their daily routine entails. We haven't learned all there is to know about Jed & Dawn, Trace & Transport and Old & New Pennsylvania though. The author left some room for growth so I wouldn't be surprised if we see some future expansion to this series. If that happens, I'll definitely pick up where I left off.
