Take a story's temperature by studying its tone. Is it hopeful? Cynical? Snarky? Playful?

Most of the text is either from Meg's point of view or dialogue between the characters, so the narrative voice isn't really a strong perspective. But in the detailed narration of Meg's experience, we get the sense that the author cares deeply about these characters, and wants us to care too, and so does her best to make us feel along with them (see "Narrative Point of View" for more on this).
