Friendship isn't always easy. Natalie is different from the other kids in Dreenie's fifth-grade class. She comes to school in a wheelchair. She always wears a knitted hat. And she's allowed to bring her puppy to class. The kids in the class call Natalie "Bluish" because her skin is tinted blue from chemotherapy. Dreenie is fascinated by Bluish and a little scared of her, too. She watches Bluish and writes about her in her journal. Slowly, the two girls become good friends. But Dreenie still struggles with Bluish's illness. Bluish is weak and frail, but she also wants to be independent. How do you act around a girl like that?
