In genre studies, a coming-of-age story is a genre of literature and film that focuses on the growth of a protagonist from youth to adulthood ("coming of age"). Coming-of-age stories tend to emphasize dialogue or internal monologue over action, and are often set in the past. The subjects of coming-of-age stories are typically teenagers.
My note: Question: Does We the Animals emphasize dialogue or internal monologue, as the Wikipedia definition, based upon film study, says? Is it a novel of personal development and maturation? What do your own further research and thinking suggest?
