Catching fire theme

The theme of my book Catching Fire is bravery! I know this is a broad theme. But it fits The whole hunger games trilogy very well. In the first book bravery is a theme because Katniss and Peeta were ready to stand up against the Capitol. They were ready to die for eachother to show the Capitol up. In the book I'm reading now, catching fire bravery is a theme because Katniss had to watch Gale be beaten by the peace keepers. Also when they were on the victory tour and one of the districts were revolting they had to be brave and continue on the tour. I will probably find a better theme as I get closer to the end of the book but for right now I think Bravery is a good theme for where I am at in the book.
