Cammie wasn't trained at Gallagher. She was trained with her three best friends, Bex, Liz, and Macey, by Joe, Abby, and her and Bex's Parents. Joe comes one day, with a mission that includes both Gallgher, and Blackthorne, she and her friends live at Blackthorne for the semester, to scare them out of their laziness. The girls think it will be fun, but be careful what you wish for.
