Peeta is chosen to be in the Hunger games. Katniss volunteers after her sister is chosen.
Katniss is in a tree when a large group of tributes is below her. She hits down a nest of tracker jackers to get rid of them. But not before she is stung a few times.
Katniss was helping aid Peeta, after the new rule was announced that two people from the same district can both win. When Katniss started making that they were in love, it made the crowd want to watch. This gave Hamon more money so they could buy medicine for Peeta, which came in the box.
Katniss and Peeta spent time hunting and gathering to prepare to face the others. While Peeta was gathering, he started to gather poisonous berries without knowing. Foxface then came and stole some berries for food without knowing they were poisonous and died.
Cato, Katniss, and Peeta all got to the cornucopia, but so did the dog hybrid things. Cato tried to climb but didn't climb high enough. He got stuck towards the bottom where the dogs were and got mauled by them. The game wasn't over yet though. Katniss ended up having to kill Cato with and arrow.
After Katniss killed Cato the game never ended. The Capitol went back on there deal of one entire district winning it. That is when Katniss had enough, if she didn't win, neither would the Capitol. Her and Peeta both took a poison berry and were about to eat it when the Capitol told them they could both live so they wouldn't be embarrassed.
