College freshmen Liesl Andrews spends her days studying pre-med and her nights stitching up werewolf bites. As a human who has the rare capacity to see the vampires, werewolves and witches who live in the shadows, Liesl pays her tuition by moonlighting as a medical intern at St. Benedict’s Hospital for the Underworld. She figures she’s doing a decent job of balancing her two lives until Jax Halloran walks into the ER. Not only is he tall, dark and obnoxious, he’s also a high-ranking vampire who needs her help. A virus is threatening the vampire community and Liesl may be their only hope at finding a cure.
