Did any of the characters change?

Over the course of the novel, Polly changes her views on slavery. Initially, Polly sees her role as an indentured service to be superior to that of the slaves. She is even offended when Mr. Derby tasks her with teaching Amari English. Polly's ability to read and write set her apart from the other workers, and as a result, she believes that her knowledge qualifies her to work inside the Big House. She does not believe that she should be laboring alongside the Africans. Over time, however, Polly begins to see the similarities between herself and the slaves, particularly after Clay begins calling for Amari in the night. It is this event, Amari's rape, that opens Polly's eyes to the similarities and injustice of slavery altogether, as she comes to understand that underneath their skin color, she and the slaves are exactly the same.
