Erin ThunderWielder is a Conjurer. Only...she's not supposed to be. She is the first in generations not to be a Diviner and for that her family has disowned her sticking her staying with her best friend Nolan. But that's not the only thing going wrong in Erin's life. A new evil is arising and for some strange reason Headmaster Ambrose is convinced she may be the Spiral's only hope.
