Fallen Destiny

Destiny isn't human and she has the horns to prove it. She's also damned good at blending into the human world. That, along with her powers, has helped her forge a career out of locating supernatural beings and objects. Got demon troubles? Need a mystical artifact found? Destiny's the one for the job. All goes well for her until the day she's hired by a mysterious nun, and for the first time, Destiny's stumped. How exactly does a demon hired by a nun find an angel?
