It's tough to be a champion for anything when you're the new kid in school and you start the year by running afoul of the school bully. Sky Maroni just wants two things: to make new friends who accept her as she is, and to fulfill her promise to be a champion for monarch butterflies, who are in danger of disappearing from North America forever. Why, then, are both things so hard for her?

Carter Hayes is a starter on the football team, the leader of a popular crowd of kids, and a bully. When he and his friends pick on Sky and her new friend Lily, Sky tries to stand up to the bullies. But it doesn't work and only makes things worse. Carter carries a grudge. Making friends has always been hard for Sky, and it doesn't help that her new friends, her only friends, are the kids that Carter also picks on - kids who have challenges of their own. Boys and girls like Sky, who just don't fit in.

Sky must stand up to Carter and his henchmen, who seem to cause trouble and heartbreak everywhere, and who put her new friendships to the test.

Sky just wants two things. Is that really too much to ask?
