Hi Angie,
I really enjoyed the book too; read through it very quickly because I couldn't put it down. I liked it for many reasons, mostly because it portrayed a world that had gone to seed, but hadn't gone to Hell, at least, not everywhere. It seemed to allow for human dignity and decency.
I agree that the ending seemed rather.... different. I was left thinking "And what just happened there...."
But, when I mulled it over, I thought it wasn't that strange.
There was always something special about the New Faithers, something different. Why did they come to the Valley? How did they manage to get through all of the chaos of the rest of the Eastern seaboard.... and mostly, how did they KNOW to come there? It's not like they Googled and found out that there was a place almost unchanged since the wheels fell off of the modern world. The valley was a place that was pretty peaceful and forgotten in comparison to the rest of what was left of the States. They still had running water, plenty of food production, and the land owner even had electricity on his property.... and this special group of Christians knew to come to this place to re-build. The leader even said that God told them to go there. And, the place needed them. They were in need of some law enforcement, some organization and some real planning (the lawmen, the water works, the laundry, etc)
Also, remember how strange things kept happening while the main guy was travelling with the Brothers? Two people ended their lives while in their presence, almost in hope of being properly buried and read rites. They seemed to have true Grace.
So, I think that you are supposed to think that in the end, humans left to their own secular devices can get pretty far (look at how the land owner managed his people so well and produced so much, yet he wasn't a religious man) but in the end, there needs to be something else, that something extra, to lean on when it comes to right and wrong and to justice and goodness, like when there was a murder in the sleepy town.
I think that you are supposed to think that Brother Jobe does represent God, either through that Queen Bee figure or along side of her. He was able to cause what happened to Wayne as an "Eye for an Eye" punishment for what happened to his son. Whether you want to picture him just phasing through the bars, or just leaving his own cell and having it happen without him near, whatever you picture, it was Brother Jobe's doing and perhaps meant to be God's will.
Remember at the end, when the legends started about "Eye for an Eye" up there in the Valley? That would have spooked some of the less desirable people when they heard it and may have put a damper on future raiding trips, protecting that special little town, keeping it precious and innocent, after the sacrifice of the Son (of Brother Jobe) was made.
Maybe the other went this route because he wanted to give stable hope to the reader in the end? That you were left with some comforting assurance that the little town would endure, because it was chosen? That the rest of the country might one day be able to be saved as well?
After I thought about it, I thought it was really neat.
Trin.
