What is the author's style in A Summer to Die by Lois Lowry?

Since A Summer to Die is told from the perspective of a thirteen-year-old girl, the language and tone is appropriate for a youngster of that age. The reader is privy to her thought process and some of the naïve and immature reactions she has and conclusions that she draws. Although Meg is an accomplished young girl and an outstanding student, she is shy and unsure of herself. We learn that she is at once envious and adoring of her sister. While Meg is the bright one, Molly is beautiful and socially at ease. All the familiar feelings that a younger sister has for an older sister who seems perfect are showcased in the story.
