Prey by Carrie Harris

Werewolf investigators. Mind control. Faerie politics. Kidnappings.
Just another day in Las Vegas.
Private investigator—and secret werewolf—Derek Ranier has been hired to track a thief. But when he tracks down escaped faerie Citrine Avonmora, he’s drawn into an ages-old contest for control of the faerie kingdom…and his heart is on the line.
Citrine Avonmora wants out. She’s tired of being a pawn in the unfathomable political games of the fae. But when she escapes to the human world, she finds more than she bargained for. Like love.
