In a dangerous hidden world filled with supernatural conflict, she may be the key to winning everything.

Olivia Markham lives a complicated life. By day, she’s a star CIA officer working a cover as a graduate student in Vienna. By night, she’s a self-appointed, kick-ass superhero wearing a harlequin's hood and wielding a wicked bō.

Life is about to get more complicated. The sexual predator that Olivia tracks one July evening to Vienna's Stadtpark calls himself Asmodeus, a demon’s name. Olivia doesn’t care what he calls himself. She’s just there to save an innocent young woman. What Olivia doesn’t know is that Asmodeus has followers he calls bogomili, after an ancient sect of believers. She suddenly finds herself fighting to save her own life against these vicious creatures whose mission is to release souls from the bonds of a corrupt world.

Across the Stadtpark, another hears Olivia’s battle with the bogomili. He is a drangùe, a powerful warrior with supernatural abilities who’s duty-bound to save innocents from Asmodeus. This drangùe will stop at nothing to defeat his age-old enemy - even if it means risking everything to bring Olivia into his world. A world in which the drangùe has his own cover identity. He has good reason to distrust this beautiful young woman who hides secrets that could get him killed or worse....

But the drangùe must keep Olivia close in order to stay one step ahead of Asmodeus. The only problem is that the closer he keeps her, the more the drangùe wants to keep Olivia in his life. And that is not part of his long-term battle plans.
