The Weight of Blood by Tiffany D. Jackson

Madison has kept a secret for a long time. Her father wants it that way. He makes her change her appearance and monitors her every move to make sure no one ever finds out. What would the people in their small town of Georgia think if they knew that Madison was bi-racial?

Even though everyone thinks Madison is white, she does not move through her school unnoticed. In fact, she is the target of bullying with her old clothes and quiet, loner status. After an incident that goes viral, Madison is exposed and things escalate quickly. 

Some of the popular kids blame her when they get into trouble for bullying so they amp it up. One girl wants to rectify her friends' behavior (although her motives are questionable), so she proposes that her black boyfriend (a popular member of the football team) ask Madison to the prom. 

One more thing: Madison begins to realize she has the power to move things and control fire with her mind. A skill that is dangerous and powerful (particularly when dealing with bullies). It also scares the hell out of father. 

This is an homage to Stephen King's Carrie with racism as a huge motivator. The town is so backwards that the white and black students have separate proms ("because that's the way it's always been"). The popular black football player has never bothered with racial issues not wanting it to effect his future in football, but Madison's presence starts to change that. Madison's father is so afraid people knowing the truth that he painfully straightens her hair and locks her in closet covered with pictures of beautiful white woman so she doesn't forget what she is supposed to be. 

The whole system is so messed up that no one in this town remains untouched by its racist past and present. Ultimately, they cannot escape the consequences either.
