Dark Waters — Allyson Gottlieb

In glittering Miami, vampires run the nightclubs of South Beach, werewolves roam the streets of Little Havana, and every day, crooked paranormals break the law in ways that would be unsolvable or even undetectable by ordinary police. Solving these crimes falls on the shoulders of a secret branch of the criminal justice system known as the Department of Paranormal Regulation.
