Fourth wall, what fourth wall? The entire book is told from first person in a reflective manner, but is handled in such a way that you are still not sure of the status of the narrator until the very end. The story revolves around a woman forced into dealing with the noble family her mother was exiled from. Throw in a pending succession to the head of the family (she's a candidate) and the fact that they have imprisoned gods at their command, and you have the potential for a lot of trouble. The interactions between Yeine and the gods living with the nobles make a very fascinating study in how different people react to power and control based on their backgrounds and personal values. That said, there are some very messed up values for the nobility that add a bit of darkness to the book. I'm not entirely sure I followed everything at the end, but it does tie together well and consistently.
