Over at Greenbaggins, a very brief review of The Hunger Games novels has been posted. It is worth reading the few short paragraphs. I believe he makes some wonderful points about violence as portrayed in the books (which I have not read, for the record), as well as how that applies to violence in our society. Further, the lack of reason for violence or reason why such violence is wrong is completely missing from the novels, per this review.
All in all, some good food for thought, especially if you or someone you know will be (or already has) read these books.
