Mike LeBonte went to prison for summoning demons and using magic. At the age of 18, he is let out for good behavior. Now he's trying to make a better life for himself.

He's trying to stay out of trouble. However, trouble finds him, because someone has summoned a demon in a local park, and he is called in to assist the police in figuring out who did it — that is, if he didn't do it himself.

At the same time, he is attempting to make inroads with a handsome young man in the city, the owner of a New Age store in downtown. Mike also assists his cousin who is being stalked by someone — or a group — while fighting off his new boyfriend's ex.

And when you think it's over, someone has summoned Lucifer. But with the help of modern chemistry, Mike doesn't have magic anymore.

This is just a few of the adventures that befall Mike, also known by his prison name: Grimaulkin.
