Quote from "The Hunger Games" stating that Katniss is the individual of the novel.

From the text:

Then something unexpected happens. At least, I don’t expect it because I don’t think of District 12 as a place that cares about me. But a shift has occurred since I stepped up to take Prim’s place, and now it seems I have become someone precious. At first one, then another, then almost every member of the crowd touches the three middle fingers of their left hand to their lips and holds it out to me. It is an old and rarely used gesture of our district, occasionally seen at funerals. I means thanks, it means admiration, it means good-bye to someone you love.
