Awesome, awesome, awesome. The author wrote in French and unfortuantely I don't think the books have been published in English (other languages yes). If you read French and like dystopian future sci-fi books you will love this one. The world has been ravaged except for Western Europe and North America which both live peacefully behind a magnetic shield that protected them from a nuclear war. Every year some refugees from Asia are allowed into Europe. Some are used for organ transplants and the others stage a real war that Europeans can watch (kinda like Running Man or Hunger Games). The main character, Wang, enters into France and becomes a leader in the war games before deciding to try to free the refugee slaves and open up the magnetic wall for good.
My explanation doesn't do the story justice but it, and the second in the series, really are sweetness! ( )
