One issue I found with the end of the novel was that there is an almost-preachy avoidance of going "too violent" with the characters. The final "war" scene has the perpetration of violence being found principally outside the main characters. I find this interesting for several reasons.
One, one of the most powerful themes in Lord of the Flies is that evil is found within us, not outside of us. In Golding's novel (written for adults), children are evil and cruel; does Ward's reticence in this area shed light on YA literature as a whole, or just Ward's personal boundaries? YA is typically perceived as having no boundaries--incest, violence, murder, rape--all have been addressed in YA literature, and Ward creates some characters who seem to delight in cruelty and evil; yet he reigns these features in for the novel's climax. Why?
Two: Can a novel's characterization suffer from this kind of authorial choice? Should a novel have a different focus or redemptive purpose if it's written to be read by children? How much "real" is too real? I think this novel offers an interesting space for discussing the role, purpose, and use of violence in children's literature.
