Magic

Ollie wasn't looking for trouble, but after she saved the Antichrist from being slaughtered, it came for her.

Ollie lived by one rule. Never get involved with anyone for any reason; humans, demons, fae folk, it didn't matter. They were all trouble. Keeping her distance was how she survived in the criminal underworld for so long.

Keep your head down and don't piss anyone off. That was her motto, especially since her clients all had access to powerful dark magic.

She thought she had a flawless system for keeping her nose clean, so how did she wind up in a stolen car, with a demon spawn in her back seat, driving away from her ex-lover and a gang of demons ready to skin her alive?

That's a good question.

And why did she agree to help save the demon's life so she didn't get sacrificed to open the gates of Hell?

An even better question.

She had one rule. One stupid rule. And tonight...it goes right down the toilet.

Now, the only way for Ollie to get her life back is to save the girl, prevent the Apocalypse, and track down the people who betrayed her.

They will pay. Oh yes, they will all pay.
