A series of Ancient Greek themed murders brings Dr. Chey Griffiths under the BAU's radar, a stubborn woman who thinks she can solve it all on her own. How will the people hating, animal loving mysophobe who's never been interested in men feel when she meets Spencer Reid. The only person who completely understands her irrationality?

Ichabod and Abbie stumble across Chey, an independent demon hunter with moxie. A formidable ally, fighter and an ambassador of Hell. Exiled from her duties for unknown reasons, Chey sentences demons to judgement on Earth and finds the town that attracts them like moths to a flame. Could someone like her allow personal feelings to get in the way of her self proclaimed duty?
