Shai happens to be skilled in forgery and creating the most unusual things is not something she is afraid to do. She got caught when she was replacing the Moon Scepter and she thinks that she is going to end up in jail after that well she was right to some extent.
Although she ends up in a small room she is not imprisoned rather she is kept in that room for an impossible task. Those who have arrested her want an impossible task for her and if she fails then she might not be able to see the light again in her life. The emperor of the kingdom is unconscious and the queen has been killed.
The people of the land think that the emperor is in mourning and they will be able to see him after a hundred days. The reality is that the emperor needs a new soul and if he does not show up after a hundred days then there would be a battle for the new heir. Shai is given the task to forge a new soul for the emperor before it is too late.
She hasn’t done such a thing before because it has been forbidden by all kinds of laws. The one who is keeping an eye on Shai is also the one who does not like her at all. Brandon Sanderson takes the audience into a strange kind of world that is narrated by Angela Lin. Just leave Shadows of Self and The Original for some time and try to concentrate on the development of the story here. You are going to love the challenges that are thrown in front of Shai.
