Mockingjay (the Hunger Games #3) - Suzanne Collins

Katniss Everdeen has survived the Hunger Games twice. But she’s still not safe. A revolution is unfolding, and everyone, it seems, has had a hand in the carefully laid plans – everyone except Katniss. And yet she must play the most vital part in the final battle. Katniss must become their Mockingjay – the symbol of rebellion – no matter what the personal cost.
