While Marra is a princess, she’s been spending the last half of her life in a convent in the Southern Kingdom waiting out her fate. Her older sister is married to the prince of the Northern Kingdom and deeply abused by him. Marra is the third princess from a super small country. The beginning jumps between what Marra accomplishes for the witch and what’s already happened. If she’s able to get the help of the witch, then she can begin her journey to saving her sister. It’s the first task of three that she’s willing to do in order to garner the help of a gravewitch. What does she needs the bones for? Well, she needs them to resurrect a dog.
