does anyone know what the main focus of Catching Fire is or will be about?

now that the games are over the Capitol is furious and there is talk of rebellion among the people and Katniss and peeta are the faces of it. I read that somewhere i can't remember where though...

I have not read the new book yet but I did hear she will be forced to marry Peeta.... But who knows!!

I have a couple different crazy thoughts, but mostly I have no idea. i just posted a similar question, "What do you think will happen in Catching Fire?". Obviously there will be a love triangle between Katniss, Peeta, and Gale...but what will the action or plot be focused on? Suzanne can't write a whole book on a love triangle.
