The concept of Pax is really intriguing. My heart felt for both Pax and his boy Peter; as the story progressed. The fact that both having a voice was really wonderful; the reader is able to watch the growth of both Peter and Pax as they lived through what was going on in their lives. The story is very well written. However some distance in to the book had me wondering how old a child would read this story and not be upset by events transpiring. I went back to see the 'suggested' age for children and thought that kid must have a strong support system. The subject matter almost had me stop reading because I wasn't sure if this ended bad that I wanted to know. Perhaps I misread the blurb, but I assumed it was about a father joining the military and not that war was rampant where the story took place.
