What is the narrator point of view in the novel, To the Bright Edge of the World?

The novel has four distinct points of view: Sophie, Allen, Walt, and Josh. Sophie and Allen are the two main narrators, through their diaries. Sophie's diary is a few months behind Allen's for a majority of the novel. Allen begins in March as their expedition is beginning, while Sophie begins in January a month before Allen leaves. As the novel reaches its' end, Sophie catches up to Allen until their final entries are both on the same day. Both narrators share their deepest thoughts, and both admit they are writing to share their experiences and emotions – no matter how happy or sad – with the other. The reader gets the rawest emotion possible, creating two reliable and relatable narrators.

Walt and Josh's point of view, however, is told in letters to each other and contains less of their deepest thoughts and more prolonged conversation. This is where the reader gets discussion from the present day about Sophie and Allen's lives. These letters do not have dates, so it is unclear how many exact years there are between the two. There are also a few writings from a Russian missionary, various medical texts, and third-person articles. All of these are brief and adopt the point of view that reflects the type of writing it is.
