Which character from “briar rose” is the narrator?

Point of View- the position of the narrator in relation to the story, as indicated by the narrator's outlook from which the events are depicted and by the attitude toward the characters.

Briar Rose is in third person from the narrator's point of view. We know this because the book does not say I, me, we, you, or us. Instead the book says he, she, it, them, and the characters' names.

The answer would be "so"
