Gilly - the half-savage heroine - is a young girl on the edge of womanhood, who lives in a Scottish forest with two older women, scraping a living from scavenging in the woods and robbing the dead on the battlefields of a terrible, endless war. She lives only for revenge against the man and woman who destroyed her young life and drove her to be an outcast: the warrior king, Macbeth and his ambitious queen. Disguising herself as a boy, she finds a way into their castle, just as they prepare to seize the throne of Scotland.
