Step-by-step explanation:
The School for Good and Evil is a fictional series written by Soman Chainani. The series revolves around a school where students are trained to become either heroes or villains. The main characters, Agatha and Sophie, are best friends who are mistakenly placed in the opposite schools. Agatha, who is more inclined towards evil, is placed in the School for Good, while Sophie, who dreams of being a princess, is placed in the School for Evil. The Storian, the magic pen in the series, is protected by the School Master in order to ensure that the stories written by the pen remain balanced and true.
