For Harmony Black, practicing witch and federal government agent, defeating criminal masterminds and eliminating supernatural threats are in a time’s function. She’s ready to fight, so long as she can depend on her partner, Jessie Temple; her group at off-the-books special FBI unit Vigilant Lock; and her magic. But her latest case threatens it all.

A high-profile bank robbery reveals thieves with the same unnatural power and turquoise eye as Jessie, who was touched from the King of Wolves. Jessie turns into unstable, struggling with her inner beast, and Harmony’s magic is threatened by unexpected interference. A whole lot worse, the ladies uncover a top secret their own handler may destroy to safeguard, forcing Vigilant Lock to set off the grid.

In the smoky back rooms of Washington, DC, inhabited with the crooked elite, towards the astonishing high-rises of corrupt upper-crust Manhattan, Harmony and Jessie combat to discover and halt a mass conspiracy threatening US soil in a competition against time—and hell.
