There is nothing obscure about Suzanne Collin's Hunger Games trilogy. The trilogy consists of The Hunger Games, Catching Fire and Monkingjay.
Set in a dystopian near future, it follows the life of a young woman who volunteers to take the place of her baby sister as a tribute from her district to the capital of the country. The tributes take part in a giant live-action reality TV show where the prize is their life and the cost is also their life.
I highly recommend them.
And there you have it from my very good friend Sumiko. She has not steered us wrong yet! Thanks Sumiko!
