Merican Literature: Tim OBrien book Northern lights

I need an analysis of this text with just a very small summary of the story (one paragraph). I need analysis of the characters: their motives, how they grew throughout the story, self-knowledge they gained, and how they gained it. Any symbolism in the story, the themes, and the settings where they are placed historically. Also if there is any reflections of society in the story.
Citations need to be in the paper and a bibliography
