Shadowcast

Teenage smut author Lisa Edelstein is the last person you'd want defending humanity from bloodthirsty monsters, especially since she's never actually seen one in person. But a midnight train ride changes everything.

One summer and a few forged transcripts later, our intrepid hero finds herself attending Ashibar Academy, a tough-as-nails high school for magically-enhanced monster-killers. With no powers, no weapons, and no combat experience, she'll have to rely on her wits and charisma to survive in the cutthroat halls of an unfamiliar school.

But when her mysterious black scars start drawing unwanted attention from a paramilitary organization, she begins to discover that there might be more to her than she originally thought. Her newfound friends may be the only thing standing between her and annihilation.
