Katniss is a pawn being used without her knowledge by those who want a revolution. All she wants is to survive and to keep Peeta alive as well. She has no idea the lengths her fellow contestants will go to keep the new symbol of unrest alive and well. I won't give details away because I don't want to spoil it for anyone, but the ending. OH THE ENDING. You'll want to have book 3 instantly available to you. Trust me.
