Do any characters grow or change during the course of the novel? If so, in what way?

I truly believe that Katniss is the one who changed the most. In the beginning of this whole thing she was kind of scared of this whole thing. She didn't know if anything was working cause she wasn't allowed on the front lines until later. Then she changed into this strong powerful speaker that motivates the rebel force. She also started caring about herself right away and later on she turned into a caring giving person like Prim is.
