What is the author's style in So Much to Tell You by John Marsden?

So Much to Tell You is written in the first-person point of view of Marina, a fourteen-year-old girl, who is the main character. Marina writes in her journal daily.

The unusual aspect of hearing the story from Marina's point of view is that she never speaks and so the outside world has absolutely no idea about any of the thoughts or feelings Marina expresses in her diary.
