Devil's Daughter - Hope Schenk-de Michele

Lucinda is as old as humanity itself, yet perpetually young, beautiful, and endowed with supernatural powers. She lives a double life-human and immortal. Born out of a betrayal of trust between the first woman, Eve, and father, Lucifer, Lucinda has worked covertly and subtly for millennia to be true to her mother's love by subverting her father's schemes.
In her human guise, she manages Lucinda's Pawnshop & Antiquary, the doors of which can open to any street anywhere in the world at any time. Mortals who have arrived at a moral or spiritual crossroads are drawn into the mysterious shop. If they acquire one of its cursed artifacts, they may find themselves drafted into Lucifer's service. And if the Devil's daughter will not love a man he can control, can Lucifer control the man she loves?
