Read the text and consider:
Who has the power in this novel?
How do we know?
How important is this power to the story?
What relationship does this character have with the protagonist (assuming it is not the protagonist!)?
If it is not the protagonist who has power… why is it not the protagonist who has power? Does this imbalance influence the narrative and how it develops?
Is there an antagonist? How much power does (s)he have? In what area of life? How does (s)he exert this power?
