There is a capital and 12 districts in a country. Each year, 2 children (boy and girl) are chosen from each districts, so total number of children is 24. And they are left in the ground and forced to fight until everyone dies except one child. This survival game is called "Hunger Games", which is entertained by people in the capital. The main character of this book is a girl living in district 12 which is the weakest district. She attends this game replaced for her younger sister chosen firstly.
In short, this book describes how she acted in this game. But it's not so boring. The content of this book is quite similar to "Battle Loyal" published in Japan in 1999. But if you don't like "Battle Loyal" because it's too crucial for you, you might like "Hunger Games". It's because "Hunger Games" is more humorous and light story.
I like "Battle Loyal" much more than "Hunger Games" as a book, but I guess "Hunger Games" is appropriate story for movie. The movie is also very big hit in US, so it's worth checking.
