 So, I am terribly behind the times and I know little about The Hunger Games book series. But apparently, it's set in a dystopian world where people fight for the entertainment of rich people? And there's  this lady called Katniss who participates in these fights.

Could anyone tell me more about this series? I've heard that it's controversial, and people have mixed opinions on it. Could you tell me your thoughts?
