Harmony Black is much more than your ordinary FBI special agent. Not only is it a exercising witch, she’s also an operative for Vigilant Lock, an off-the-books plan created to battle occult threats-by any means required. Despite her dedication to fighting the monsters threatening society, Harmony has become deeply conflicted about her job. Her last investigation led to a pile of dead body, and she suspects the wrong people are getting punished for it.

While in a much-needed holiday, Harmony gets pulled back to action. This time, though, she’s eliminated from solo function to being portion of a group. Their focus on: the Bogeyman, a vicious and elusive number…as well as the creature that destroyed Harmony’s childhood.

Surrounded by quirky, interesting characters as focused on one another because they are to their new partner, Harmony must learn to trust her team-and a fresh romantic interest-on an unhealthy and deadly mission that conjures up memories she’d much rather neglect.
