The author's purpose is to give an example of a disadvantage or unfairness between being colored or being white and make the reader more sympathetic to the circumstance.
Idk maybe look on google if not look up just telling of epics and it might say it in there
I would say it an euphemism
In the book all the characters are perfectly fine living their life’s being controlled by Society. But Cassia is not fine with this. She stands up for herself and stands by her morals. This book gives us an insight on society today. It gives us an insightful message not to succumb into the plain everyday life that everybody does and give society a run for their money. Or it could mean hang on to your own thoughts and be yourself, don’t let them change you. It also means to put up a fight, if the society says you are doing something wrong to prove to them and everybody it is truly right.
