High school is all about boy meets girl, girl gets demon mark, and girl finds out she's half-angel. At least that's how it is for Ginny Gracehurst.

Sixteen year olds have a lot going on in their lives, and Ginny is no exception. Grades, homework, pimples, oh and now the sudden appearance of a demon mark. And discovering her father-who she thought was dead-is actually the great angel Grace. Who is very much alive.

With unforeseen powers growing, she has to figure out who she really is. While also staying out of the reach of a powerful half demon who is hell-bent on bending her to his will. The Alliance, an organization that is supposed to help people like her, is threatened by her potential gifts. They are more invested in their own hierarchy than in upholding their divine mandate. It's up to her and a new friend, Aiden, to protect not just herself, but the ones she loves.
