There is an underlying issue to the hunger games this year is that Katniss must prevent a district wide revolution against the capital after her stunt with the nightlock last year with Peeta. Even though all she was trying to do is keep her and Peeta alive , the fact that she inadvertently rebelled against the capital is just a fringe benefit. The ironic is that as much as Katniss and Peeta try to keep up the ruse that they are in love, to try to keep calm and peace in the districts, a rebellion has started in various districts that Katniss cannot control. Katniss even decides to join in the fight against the capital through standing hand and hand with the victors, and hanging last years head game keeper metaphorical when she is getting her score before she enters the hunger games for a second time. These little acts of rebellion in addition to the riots from districts three and eight light a fuse in which the districts would like their free will taken back from the capital.
I think the main theme seen throughout this whole book is free will or rather lack of it by the end of it. (spoiler alert) By the end of the novel Katniss is freed from the hunger games arena and learns that District 13 and many others are trying to overthrown the capital once and for all. Katniss learns that she has become a pawn for the second time, that Haymitch has betrayed her trust through not informing her about the revolution and that she now is the symbol of this revolution which plans to have a coup on the capital. Katniss has not had much free will throughout both books, she had to fake her relationship with Peeta to survive, now she has become part of a battle she is not sure if she even wants to fight for. I state this because of the many instances in both books where she mentions running over with Peeta or Gale to no longer be under capital rule and be free. However this theme of their not being any free will in a dictatorship based society has been seen in such books as 1984 (maybe Brave New World, am not sure about this), and many others.
This book also has many questioning my own decisions in life, do I decide things, am I influenced by others, or is it already predestined and I have no say in the matter. Also this question becomes even more complicated in a social networking world with blogs, social networking sites, etc. These outside influences could impact how we view a restaurant, our friends, family, etc.. I think the problem with this that all these outside sources are based on perceptions when the reality about certain establishments, people, and events might be totally different. So do we make our own decisions, or does the internet do it for us like with Hitchhickers guide to the galaxy that will tell you everything you need to know and helps make decisions for you.
