How would you describe the author's tone in The Hunger Games?

The author's tone in "The Hunger Games" is almost as
chaotic as the story itself.  The text itself is written from a first-person
point-of-view and this particular narration allows readers to see exactly what the
protagonist (Katniss) thinks, sees, and believes.  Therefore, the tone of the text
changes as Katniss changes.  At times, the tone is strong, willful, and promising. At
other times, the tone is fearful, angry, and scrutinizing.  Both the tone and Katniss
change as the story line changes.  Readers can find themselves anxious, angered,
enamored, and strengthened in the same ways that Katniss does- this all because of the
tone set in the novel.
