Because of Anya by Margaret peterson Haddix

The Characters do seem real and believable just by the way they act. The act like they are the ones that actually tell the story. The way they act shows that they are believable and good people on how they care for anya. Anya is the one with the hair cancer. She was trying not to show it or let anyone find out about it. Although the way that she acted and the way it looked gave it off to some girls in her class. Especially it being the same as her real hair and how it looks exactly like her real hair, it still shows no matter what it looks like.
