Dynamic Character

The book I'm reading is called Undercurrents. The main character is named Nicole, Nikki for short. 

"...,and for a moment we stood there, smiling at each other"

 

          Nikki's mom passed away and she can't get over it. A month or so later, her dad gets remarried to a girl that's just a bit older than her older sister, Bonnie. Nikki feels as if she'll never get along with Crystal, the stepmom. Nikki thinks Crystal is strange and weird. Crystal wouldn't let Nikki go to a job she got, so Nikki got furious with Crystal. They wouldn't talk to each other for the whole day.

          A day later after they weren't talking to each other, Crystal dyed her beautiful blonde-silver hair to muddy brown. Sam and Nikki saw it and were super shocked. Crystal ran upstairs crying and Nikki went after her. When Nikki was trying to cope Crystal, Crystal told her a story for why she's done these strange things. When she was little, she was the only survivor of her family's attack. Crystal hides away her hair and face because she doesn't want to be noticed. She doesn't want to drive Nikki to work because she doesn't want to go out often, she doesn't want people to see her and recognize that little girl whose family all died. She died her hair so that people wouldn't see that familiar hair of hers from long ago. That night, a fire came up at the Gyasi's home. Crystal and Nikki rushed to their home and saved them.

           Now, Nikki doesn't think strangely about Crystal. Crystal and Nikki talks normally now, as if they were mother and daughter.
