Someone's importing illegal metals into Las Vegas. Iron, to be specific: the only substance that can instantly kill one of the deadly sidhe. But there are no sidhe in Las Vegas. Not anymore. Dana McIntyre killed the last of them two weeks earlier.
Importing the iron seems to be a matter of life and death, though. Mostly death. People are being slaughtered over these imports, and Dana can't figure out why. It's a puzzle that must be solved quickly and quietly. If the Office of Preternatural Affairs realizes how destabilized Las Vegas has become, they'll shut down vampire hunters like Dana.
She has no choice but to partner with Nissa Royal, the right hand of the city's master vampire, to hunt down the iron's buyer. Nissa's interested in a lot more than a functional partnership from Dana, though. She wants her soul. And she's not going to settle for anything less.
