Sometimes children do horrible things. Sometimes children are horrible things. Well, in fiction, at any rate.
Melanie spends most of her life alone in a cell. Every weekday morning she is bound by soldiers that handle her with prods and cuffs, then take her to a schoolroom full of similarly restrained children. There Melanie, with her voracious and brilliant mind, learns a great deal about the world that used to be. Her favorite lessons are from her beloved teacher Miss Justineau, who teaches her about the Greek myths.
Slowly Melanie learns that her life is the way it is for a good reason. At first she cannot believe she is so dangerous, but she bravely, impressively, does accept it. In fact, she practically embraces it, using her power to protect the one person she loves.
