What is the author's style in Scribbler of Dreams by Mary E. Pearson?

Because the novel "Scribbler of Dreams" is told in the first person perspective of Kaitlin Malone, a seventeen year old writer and high school student, the language reflects her character. The novel is told in poetic prose, reflecting Kaitlin's literary talents. Yet the writing, though poetic, is by no means full of polysyllabic words and intelligent language, reflecting Kaitlin's rural roots and pre-college education.
