Abby Hendrix keeps an ax next to her living room couch. Most nights, it stays there untouched while she snuggles under a pile of blankets and reads the latest book from her favorite gothic horror novelist, HHR Eventide. Her life as an accountant in her quiet hometown in northern Minnesota is mundane. And she's just fine with that. Her only real problem is, every time her strict sense of virtue falters, a demon from Hell climbs up her basement steps.

That's what the ax is for.

Abby has become fairly practiced at slaughtering these hell-born abominations before they reach the surface. Her existence, as tortured as it is, has become routine. That is until she meets Eric, a friendly electrician with a smile like a yellow lab who sends her moral compass spinning. He's been hired to make repairs directly underneath the courthouse where Abby works, which means there's nothing between him and the things from below.

If she's going to keep Eric safe, she must remain pure of heart and mind, or go to the place where her demons live and attack them head on.
