Meet Callie Penrose, a rookie spell-slinger from Kansas City.
She hunts monsters for the Vatican… Part-time. Like a glorified wizard intern.
One problem. You won’t find her in the church pews during Mass or teaching Sunday School to kids. Faith has never really been her thing. Especially not after being orphaned on the steps of the church as a baby.
But coming face-to-face with the Agents of both Heaven and Hell might just make a believer out of her yet. Especially when they all seem to know more about her past than she does. And that their orders are to either recruit or kill her.
Leaving Callie with only a single question - a leap of faith...
