The strongest theory

Survivors of a plane crash, children are isolated on an island. There will in this novel to the creation of groups 2 and 2 modes totally opposed. One wants peaceful and emphasizes diplomacy, the other is based on force and violence.

I struggled to get into the story and I admit, struggling to finish the book. However, I can not deny that this novel is a critique of the social patterns (the fittest) development level of the children.
What will happen when a group of children must learn to manage, it is the method that will dominate survives? Although I have not enjoyed, I note it a quality, namely that it is the impact of social patterns in the behavior of the population.
