To save Sin City, she must battle Hell. Too bad the odds are against her.
Beneath the glitz and glamour of Las Vegas lies another city. A secret city in plain sight, full of warlocks and demons, shapeshifters and golems. A city that feeds off the chance magick that is generated by gamblers and which is ruled by mysterious beings called the Oddsmakers.

It is in this strange underbelly of the occult that Anne Moody runs a cursed pawn shop for the desperate, the curious, and the magickally inclined. Though the job is boring, it keeps her under the radar. None of her customers have any inkling that she is a dragon sorceress with a power that's been feared throughout history. However dragons are no help when a stone statue ends up in her shop that is more than it appears. The statue is a gargoyle named Vale, who is shrouded in mystery and secrets. When she learns that Vale is possessed, and that the person responsible for cursing him plans to take over Las Vegas with a horde of demons from Hell, Anne realizes it is up to her to defy the Oddsmakers and save the city, and possibly the world.
