Mockingjay (The Hunger Games 3)
Katniss Everdeen goes to war.
Collins billed this as the last Hunger Games, and she was not wrong. Of course, Katniss is no longer a child, and she is the mockingjay. We know her style in the arena, now. Once again, one way or another, for better or worse, it's time to head for the cornucopia and end it.
Throughout the stories, we have known that Katniss would do extraordinary things, and we have wondered whether her final answer would be Peeta, or Gale, or neither. The answer is here, of course, and Collins pays the toll: before the end, I didn’t know who it would be, and after then end, the conclusion had been obvious since the first volume.
