Looking back at the entire series as a whole. It's about an awkward teenage boy going up to be a man. By the end he's grown up, actually we get to see that whole group from the village grow up. Their personalitys change as they get older. If you look hard enough you can see the version of themselves from the first book deep down. One of the characters gets put into a situation where they are in charge of thousands of people's lives. And when they realize it they are like well I don't want to be here, I'm not a leader. And when they try to leave someone says well who else is going to lead us. And he sits there and thinks a bit and then curses as he realizes he has to lead them because there is nobody else. If you have trouble getting into the mood maybe you just need someone to read it to you and give the story some spark.
