Meet Me by Moonlight

Her mother called her "the Devil's girl," and Grace grew up believing it. She now works in a brothel in the failed mining town of Silver Bough with nothing to look forward to but the slow fade of day into night. Soon, she'll be too old to keep around, so Grace feels her only recourse is to trick a man into loving her and whisking her away from her life as a whore.
Grace teeters on the edge of madness and despair. Some nights, she imagines herself wandering into the wilderness, never to be seen again. She's in dire straights; her only options are a loveless marriage or disappearing into the desert to face certain death. Then, everything changes with the arrival of a mysterious stranger who claims to know all about her past.
This stranger wants to show her who she really is, but Grace finds the truth crazier than fiction. She's flung into a world of dark forces, frightening apparitions, and near-certain destruction. Does she have the strength to survive her own fate? Will she allow others to control her, or will she draw on her inner power to save herself and rise about the lost and the fallen?
