may not be very helpful but here is a brief summary basically,
Starr has overcome internal struggles over the course of the novel. In the beginning, she was scared of speaking up and worried that her perspective wouldn’t make a difference in the long run. Her vow at the end of the book never to be silent is indicative of her transformed viewpoint. There will always be injustice, but at the same time there will always be people willing to dedicate themselves to the struggle to make things right. Starr realizes that she can’t fix the world singlehandedly, but she can use activism as a tool to fight injustice. Ultimately, she embraces the power of her voice and becomes intensely aware of its ability to make tangible, meaningful change.
