Odette Zyskowski, a girl who likes keeping lists, starts a new one: Things That Aren't Fair. At the top is having to live on the road in a cramped RV with her annoying young brother, Rex, while they and their parents go on a long road trip to Grandma Sissy's. However, when they arrive, Odette learns what it truly means for something to be unfair, and learns that even though some things are out of her control, she can still try to make things right.
