Caine Valorian and his Otherworld Crime Unit crack all the unusual cases before any humans take notice. When a young woman is found ritualistically murdered it's his team of professionals with paranormal gifts who must stop the nameless evil stalking the streets. But the toughest case of Caine's 200-year career gets even harder when a new member, Eve Grant, is assigned to their unit. Not only is she green and eager to impress, she's human.

As they sink deeper into the workings of the case, Caine's attraction to the alluring Eve is causing his blood to boil. And with war brewing between species, the all-consuming passion between a human and a vampire won't be the only thing to spill on the city's mean streets.
