Hunger

Let's just say it again: The Hunger Games is such a Crisis novel/movie/universe, and Katniss is such a Hero. She volunteers to save her sister at risk of her life,  gives her (likely-Nomad) mother the what-for after the Reaping, and changes the world just through trying to survive. Nomad Haymitch - winner of the games 24 years before - displays Bad qualities so perfectly while also being the best hope of Katniss and Peeta, with his practical and honest assessment of the situation and what is really needed to have a chance. The victory is won through the teamwork of the two District 12 tributes, plus of course Katniss' working with Rue - while the Careers work together as well.

Then the events of the first part lead into a massive change in the way the world works, in part with a "revival of civic authority," as "people begin to locate themselves as part of a larger group." No coincidence, again, that it is happening roughly 80 years after the Treason that started the Games in the first place, placing these events where a new Crisis would be expected.
