Zaza and her two best friends, twins MJ and Juju, are concerned that a new boy at school, Chauncy, is being bullied by a small group of kids. The girls seek advice about how to deal with this situation, but the girls want to handle the problem on their own. They do not want their parents to call the teacher or the principal about it. In class, their teacher, Mrs. Hill, is teaching a unit on the solar system. The students are assigned small group partnerships to select a place where scientists say there could be life in the solar system outside Earth. Juju, Zaza, and MJ were selected to do their report about Europa. What seems coincidental: a stuffed animal given to Zaza by her Poppi (Grandfather) turns out to be a conduit from a member of the Supreme Council of the League of Sanctuaries on Europa, an organization that fights bullying throughout the galaxy. Zaza and her crew have been chosen to be the representatives of the League of Sanctuaries to help fight against bullying on Earth. But first they must travel to Europa for training.
