What is the author's dominant method of communication--dialogue, description, narration, exposition, inclusion of others' texts--?

Leif Enger uses mostly dialogue, description and narration in Peace Like a River. Everything is from the perspective of Reuben Land, who is an adult looking back at the time he was eleven years old. The story is a narrative, obviously, so most of what Reuben says is simple description of what happened, who said what, and how he felt about it. It is interesting, I think, to see how Leif Enger creates Reuben as an eleven year old boy throughout the story, but it is written in past tense and at the end of the book the audience truly comes to recognize that Reuben is an adult writing about his life at eleven years old. Everything Reuben experienced Enger relates to the audience through a much younger perspective. It is almost like Enger takes on an entirely different persona than his own, and then through that persona tries to figure out how that person would be like as a young boy. It seems quite complicated.

Enger's most convincing passages, I think, were the ones in which Reuben related both facts and emotions, not just one or the other, such as when he described the miracles he witnessed his father perform. If Reuben provided just facts about seeing his father walk on air, the audience would draw their own conclusions without necessarily the depth that Enger wished them to. If Reuben didn't describe the scene with lots of details and only provided how the incident made him feel, the audience would have nothing to base their opinions on and find him incredible. Enger found the right ratio of facts to emotion. He provided, step-by-step, what Reuben witnessed, and then he described how compelled Reuben was through that incident. It was almost as if Enger led us to draw our own conclusions, but based on what we were given, we had to believe Reuben.
