Naiá Lusvarghi I read it first when I was 13. It was way too early. To understand this book, the person needs to have a grasp of politics, world history and religion. I'd say they should be 16, at least. But I'd recommend it for someone who is about 19, because there are scenes of sex and violence, but mainly because this book tends to destroy the belief in humanity, so let them have it for a bit longer.
