I've read the whole series.  I think in the first book my favorite part was probably either the introduction to Katniss or when she volunteered to take Prim's place in the games.  I think these moments really share who Katniss is and who she will become.  In the second book, my favorite part is really the arena for the quarter quell.  It is both horrifying and elegant at the same time.  In the last book, I like the ending.  While it isn't the ending I thought would come, it is certainly interesting.  The characters have all found some sort of peace even though it isn't always complete.  Some how this lack of happily ever after makes the story seem far more real.

I really enjoyed the novels and one of my favorite parts of the first novel is her tenuous friendship with Rue, one of the other tributes in the games. Katniss is able to play with honor and show her humanity, even in the midst of the unthinkable demands of the games -- that it is absolutely necessary to kill everyone else in order to survive yourself.

I have two favorites.  One is where Katniss uses her brain to figure out how to destroy the supplies that the careers have.  I like that because it shows intelligence.  Then I like the part where she's going to commit suicide with Peeta. It shows standing up for what you think is right.

I have read it and my favorite part is when Katniss uses an arrow to remove the apple from the pigs mouth in the gallery of the gamesmakers during her tryout in training.  I think the series ended perfectly and I don't think there should have been a fourth book.
