Catching Fire

One of my favorite books is The Hunger Games. I read it earlier this year and it was very good. Ive now started read the next book in the series "Catching Fire." So far i have read all of part one. Once i think  i know whats going to happen next the unexpected  happens. I just found out that Catniss might have to go back into the hunger games because its the 75th year of the games. As for Petta maybe not since there are two guys to choose from. I also found out that there may be a possibility that there may be a thirteenth district. Most of the districts are starting to rebel against the capital. Im not sure of what is going to happen next.
