Devil in the Details by Christine Pope

Winning at poker is easy when you’re part demon. Staying alive is another story.

Caleb Lockwood thought he was done with Hell’s games after banishing a high-ranking demon from Las Vegas. Now he’s focusing on moving into his new, fabulous house and staying under the radar — until a local poker tournament catches his eye. One last chance to prove he can win without supernatural help seems harmless enough.
Delia Dunne has enough on her plate handling ghost clearings and real estate sales without worrying about her part-demon business partner’s gambling habits. But when suspicious buyers start circling Caleb’s properties and fellow players drop like flies, she realizes the tournament is more than a simple game of cards.
As demonic signatures multiply across Vegas and mysterious energy grids activate beneath the city, Caleb and Delia uncover a sinister plot involving possessed real estate agents, mystical ley lines, and a corporation with ties to the underworld. The final table isn’t just playing for money—they’re playing for souls. And the house isn’t just rigged…it’s hungry.

With the help of a cryptic supernatural investigator and a dwindling supply of holy water, Caleb and Delia must expose the true stakes of the game before the desert city becomes a literal Hell on Earth. But in a tournament where every player could be a demon in disguise, the only winning move might be not to play.
