Grade 8-11–Tiny senior-class genius/spitfire Jane Jarvis is seriously out of place in St. Teresa's Preparatory School for Girls in Providence, RI. Although she considers herself to be above the school's traditions, she wants to help her clueless best friend, Ally, obtain a good freshman sister at the annual Big-Little ceremony. Alas, when Ally forcefully vomits in front of the entire student body, she needs more than Jane's help. After a brief period of avoiding her schoolmates, all of a sudden she's cool, gorgeously attired, confident, and sophisticated. Well, everyone knows that high school is hell, so it makes semi-sense that demons abound, and Ally has sold her soul to one. Jane is determined to save her.
