AJ Vanderhorst's Books
An alternate USA where monsters prowl. Secret forest societies. Forgotten magic.
A monster-control academy where battles are as common as breakfast.
And that's just getting started.
Casey Grimes is invisible. Really. But that—along with a whole lotta other things—is about to change.
Monster-control classes begin for Casey & Gloria, but there's one little problem: A secret enemy who's playing for keeps.
