Hexed: The Harlot and the Thief #1 — Michael Alan Nelson

Luci Jennifer Inacio Das Neves (most people just call her 'Lucifer') is a supernatural thief-for-hire, stealing wondrous objects from the dark denizens of the netherworld for her mentor/mother figure, Val Brisendine. But when Lucifer accidentally unleashes a terrible evil from one of the paintings hanging in Val's art gallery, will any of the tricks up her sleeve be enough to stop it?
