The Hunger Games. Book 3: Mockingjay

Katniss Everdeen, the “girl on fire,” has escaped the fiery hell of the Quarter Quell, but the cost has proven far too high. Her home, District 12, has been reduced to ashes, and Peeta has become a prisoner of the Capitol, where he is subjected to brutal torture. Now Katniss finds herself in District 13 — an underground citadel of rebels whose existence had once been little more than rumor.
While the leaders of the resistance devise their strategy to overthrow the despotic regime, Katniss must make the most important decision of all: is she ready to become the Mockingjay — the living symbol of the revolution? To change the future of Panem, she will have to become a weapon in others’ hands, sacrifice the personal for the common good, and bear the burden of responsibility for every life lost in this bloody war. In a world where the line between truth and manipulation is disappearing, Katniss must find her own voice to change the course of history once and for all.
