Katniss and Peeta have been forced to enter the arena yet again. Their victories in Hunger Games and Catching Fire were insufficient for the Capitol's cowardly scum, and Katniss and Peeta (along with dozens of other victors) must take part in a special round of the Games. This round will change everything. For everyone.
The Games go badly, and Peeta is taken hostage by the Capitol. The President, who has developed an intense hatred of Katniss and Peeta over the past year, makes it his personal goal to torture Peeta beyond all recognition.
Katniss has endured more, lost more, and been hurt more than any other tribute in the Games. She has to somehow find it within herself to pull it together for Peeta, and for the people of the districts.
In a dramatic ending to a wildly climactic series, Katniss is faced with the opportunity to physically lead her people in a new direction. She shocks the world, and herself, with her choice.
Best. Series. EVAH. Run along now and read it up today, people!
