God wills it. A Saint must find a way.

All Tommy Nolan wants is some peace to enjoy his family. He’s been to hell and back, and now he needs a break. But evil doesn’t need to take a breather, and now the Vatican is back on his doorstep asking for help. A nearby monastery has been desecrated and the exorcist monks murdered in the most brutal ways imaginable. A legion of demons is gathering for something big, and Tommy’s the saint they need to help.

An old enemy is the ally he needs, but can Tommy trust him? Can they track down all of the demons in time?

And what does the Necronomicon have to do with it all?
