A tonal shift occurs as Frenchie, the novel's central narrator, loses more and more of his child-like innocence. During approximately the first third/half of the novel, Frenchie's tone is bleak, but unsure—he is still a child, lacking confidence in his own abilities and discernment. He behaves petulantly at times, allowing this childish tone to shine through, as in the following passage from "Back into the Woods":
I shrugged back into my pack and dragged my feet to follow Miig, upset that I had news I couldn’t share, especially with Rose, who looked at me now with curious dark eyes. I could have dragged that story out for a mile at least, could have spoken in a low voice so I’d have to stay close to her ear. Maybe even thrown an arm over her shoulder. Frigging Miig, so bossy. RiRi and Slopper were right, who died and made this guy Chief? Wanted all the info for himself first.
In this excerpt, Frenchie expresses childish anger at the thought of being unable to share information with Rose, focusing solely on whether or not he can impress her. His tone is antagonistic and petulant. Once Frenchie realizes the reason behind Miig's decision, he loses this petulant tone. Frenchie's realization in this scene represents a tonal turning point in the novel.
As Frenchie bears more responsibility, his tone shifts to one of greater seriousness and maturity. The bleakness and helplessness in his tone give way to confidence, pragmatism, and urgency, as Frenchie takes on the role of a leader.
