When seventeen year-old librarian wannabe Claire Daly is dragged kicking, screaming and cursing from everything she loves—her mam, her cozy Irish village and the dreamy boy next door—to take up arms in the battle of good versus evil, she learns the hard way that sometimes you don’t get to choose your own destiny, destiny chooses you.
Claire’s life plan is simple: head off to university to get her degree in library studies, summon up the courage to tell her best friend Chas that she loves him and live happily ever after. She never once entertained the idea that she might possess divine powers, that she might be predestined to battle Hell’s demons, or, to complicate matters further, that another love of many lives past might turn up on her doorstep.
But life doesn’t always go as planned, and when a co-worker is viciously attacked by a demon and her own family threatened, Claire must face the truth: she is called to a higher purpose and has no choice but to answer. Claire sets aside her dreams and begins learning how to deal with the Unholy once and for all. Armed with only a crash course in soul saving and her wits, she gears up for the ultimate show down in Hell. But will it be enough?
