Being a princess probably sounds nice. A life full of luxury, beautiful dresses and nice shoes but for Hazel, there is nothing nice about being a princess. She can never go outside the palace, she can never have friends, she can never eat or say or wear whatever she wants and she can never choose the person she is going to marry. Soon she's getting married to a man she has never met, a prince rumored to be Son of the Devil.
