Basically, spoilers start here!
Okay, so Katniss is continuing her first person narrative and she's gone through all the Reaping and the going to the Capitol and encountered an entirely different way of existence (I was going to write 'life' but really, what they do in the capital, is that life or what? Since all of everything is Life, I guess it is but it just seems like a fakeness, a mockery...)
Chapter 7 shows Peeta and her going to the training center, and meeting the other Tributes. The training center is, quite literally, a place for quick training of skills which might be useful to survive in the games. It's also a place where the Games makers see what the Tributes can do, and perhaps plan their terrors accordingly. Katniss is tested ... and they give her no attention. So she shows a little attitude and shoots the arrow through an apple in a pigs mouth -- from which the Games makers are feasting. That definitely got their attention -- and I suspect the attention of President Snow.
So far it's been a District 12 thing - then Peeta asks to be coached separately. WHAT?! Betrayal? No. It turns out that Peeta is in love with Katness. And that turns into a larger betrayal (so she thinks).
Part II - The Games
Colour Katniss pissed. Letting everyone know she is pissed. All along, though, the pageantry of the Games continues on and she is swept along with it to Chapter 11.
And the GAME begins. So far this is a story of a girl stuck in a terrible situation and it's all mostly her-her-her. Understandable in many ways. Survival is the name of the game. But now she is expanding her awareness to those around her -- she needs to know who and what they are because she wants to live. She is also, for the first time ever maybe, struggling with the concept that someone might actually love her. Her. Her relationship with Gale is so nebulous in many ways. The shell in which she has encased her 'self' is not only starting to crack, it's starting to disintegrate. Add to that she is dehydrated, and feels she is about to die.
Then she finds water. And lives.
I'm actually starting to like Katniss now. I don't know why or how this happens, but it's happening. Also, even though there isn't much in the way of detail about other characters (because of the viewpoint of the narrator perhaps?) there is enough to see that things are not always exactly as those in control at the Capitol would like them to be.
