Gilded Dreams by Thora Woods

Gold and jewels may fill the hoards of legend, but these dragons want so much more.
Korona Drakona Hotel and Casino sits like a shining beacon in the center of a neon ocean. Perfectly positioned for Viktor, Gavril, and Felix to see every inch of their kingdom. Only one piece remains before their control is complete: Somnium. Owned by a demon who refuses to yield, the strip club and den of dreams has eluded them for nearly a century. Poised on the edge of victory, the dragons cannot afford any distractions. Especially not from a red-headed, foul-mouthed brat who refuses to be tamed.

She was promised the world, but was given gold-plated prison bars.
Lyra Spanos is used to living in a cage. Doomed to an eternity of service, she’s stuck behind the bar of the seediest underground club in town with no hope of freedom or escape from the demon who owns her soul. Literally. Every night, she’s forced to watch him drag the tourists of Las Vegas into his trap. But the night they parade into the club, everything Lyra thought she knew goes up in dragon smoke. She may have been traded like a poker chip, but she’ll be damned if she goes down without a fight.
