From the way Mockingjay ends, Catching Fire should have started something like this:
I have just gotten back from the Victory Tour and I now sit with Prim in the living room of our new house in the Victor's Village. She is stroking Buttercup, and feeding him treats, while she asks me questions about the tour. I answer as honestly as possible, and so far she knows that I am engaged to Peeta. She almost called me Katniss Mellark once, and we were laughing our heads off. She is still on the market for the next Hunger Games, and so are Gale's brothers. If they were reaped, I would have to mentor them, I don't think I could do that. So, I hope they won't be, and I haven't tried to reassure Prim she won't be chosen, because we all know how that went the first time. She seems to be perfectly fine though.
It is the day of the reaping, and I sit up straight, Peeta on my left, the mayor on my right. Effie glances at me from the corner of her eye, she can see my worry. I glance into the crowd, my sister, her eyes glistening with tears she's trying to hide. I can't look anymore, so I see Vick. He is confident, and stares directly at Effie, he gets this trait from Gale, I know.
Effie says her usual line before the video, which no one watches. "Ladies first!" she reaches her hand into the bowl, and I bite my lip. My worst fears have come true. I put my head in my hands, Prim looks at me, she isn't crying, she has matured much. Peeta glares at me, there is a tear building in his eye, he loves Prim as much as I do. Effie goes to the boys and picks, another one of my worst fears. "Vick Hawthorne." I can't stand this, I want to leave, I want to go huddle in a corner somewhere. I know Gale is feeling this too, but he trusts me to help his little brother.
I have a brief meeting with Prim in the room, I was in last year. "Prim!" I hug her, as tightly as possible, a peacekeeper comes to take me away, and I shout, "I'll see you on the train!" Gale runs into me, and stares into my eyes, "I never thought this would happen, neither are strong enough." He says.
"I'll try my hardest to keep them safe,"I say, and am taken away to the train.
