Does Prim get selected for the Hunger Games after Katniss volunteers?

*Spoiler Alert*

She goes to the capital with Peeta Mallarck, the boy tribute, who has had a crush on her for a long time, only she doesn't know it. One by one, the other contestants are killed, leaving only her, Peeta, and a dangerous tribute from another district. The gamemakers announce that this year, two tributes can win if they are from the same district. After the other tribute dies, they expect to be taken to the Capitol, but the Gamemakers announce that they have changed the rules back and only one tribute may win. Katniss realizes that they have to have a winner, so she gives both Peeta and herself poisonous berries and, at the last moment, the Gamemakers panic and allow them both to live.

However, the Capitol thinks that she is trying to mock them, and her only excuse is that she was too hopelessly in love to notice. So she and Haymitch have to convince everyone that she is totally in love, even Peeta, who believes it. But at the end, he finds out that she was faking it (or was she?) and things get awkward.

But this is the start of the rebellion against the Capitol.
