Clary's fate is reminiscent of the fairy tale about Cinderella: after the death of her father, the girl was left to live with her mother and evil sisters, and her life became like imprisonment, without a single chance of salvation. Clary's world is unusual. There is always a place for magic, dragons and even vampires living in the Forbidden Forest. Many years ago, a peace treaty was concluded, according to which humans and vampires are separated by the border of the Forest. But it was violated by one of the parties, which invaded the lands of enemies and tried to destroy them. One day, Clary will cross the border of the kingdom and set foot on lands alien to her. But who is she destined to meet there: the mysterious inhabitants of the Forest or a beautiful stranger? This meeting can influence the course of history, but is the girl ready for such changes or is she quite happy with the role of Cinderella?
