You have the right to remain magic.
Any spell you use can be used against you.
After a disaster of a ritual where the Marshal of Magic accidentally unleased twelve demons into the world, he's been tasked with a mission.
Hunt them down and stop the witches who summoned them.
Twelve tasks, like Hercules, except he's only got a ghost for company.
And trouble.
Lot's of trouble.
When the first witch pops up in New Orleans, the Marshal is sent on a mission.
Stop her.
At any cost.
Before she starts the end of the world.

Fans of fast paced urban adventure with some comedy tossed in are going to enjoy this series.
