I've been reading 3 dystopian series, The Hunger Games, Book of Ember, and Divergent. I'm currently reading the Allegiant, the last book of the Divergent series, and found the similarity among those books. I read the Hunger Games first, and then the Book of Ember. I've never read the Battle Royale, a Koushun Takami's novel before, so the idea of the hunger games seems new to me. but one of my friend told me that the idea of game in the Hunger Games is similar to the game in Battle Royale.
So far, I think that the Divergent series's ideas are the combination of the hunger games and the Book of Ember. it has the same idea about the upcoming system after the big war, when people get separated by their similar characteristic in particular community. In hunger games people get seperated by their specific commodity to complement 1 central district, and in Divergent, people get separated by the value they want to practice in their life and support the others community. the Divergent has the same idea with the Book of Ember about the life outside the heroine's community, both take place over the ruin of The United States. I'm highly recommending the Book of Ember for kids and the Hunger Games for the teenagers, but quite dissapointed about the Divergent, particulary because of ther are so much unnecessary intimate scene between tris and tobias. haha. waiting for might coming supprises in the last book that could possibly change my perception.
