A young human woman is found ritualistically murdered in a downtown Necropolis hotel. It is up to Caine Valorian, a 200-year-old vampire, and his Otherworld Crime Unit to solve the unusual crime, and quickly before the human press can jump onto the story and cause a panic. To add to their already tough case, a new member, Eve Grant, transfers to their lab at the request of the mayor. Not only is she green and eager to impress the boss, but she's human. The first human ever to work in an Otherworld unit. The mayor thought it would be great press especially now with the strange human murder.
Caine has his work cut out for him, especially with his unruly team who don't appreciate any help from a human. Not only is this the toughest case of his career, but he's unusually attracted to the new girl, which can only cause trouble for them all. However, as they sink deeper and deeper into the workings of the case, Caine and Eve become closer and closer. So close that neither of them can see past each other and at the real happenings behind the scenes. The more they poke and prod at the case, the more they realize that something is going on, that this murder is only one step toward a greater purpose. Someone in the Otherworld community is calling on dark forces, in a plot to wipe out the entire human population.
