Blood Secrets (4), by Vivi Anna, introduces vampire detective Caine Valorian. Caine's domain is Necropolis, a city that exists within the human world yet apart from it. When a human girl is found murdered in Necropolis, Caine and his team of werewolves,vampires and witches are forced to work with Eve Grant, an alluring human investigator. Soon, Caine finds himself in the midst of the greatest and most forbidden attraction of his life. As it becomes clear that the attraction is mutual, it becomes even more important for Caine to solve the murder -- before his relationship with Eve compromises her life. Anna has written an absorbing and romantic love story that will not disappoint Nocturne fans. Caine and Eve are beautifully drawn, and their banter is as hot as their love scenes.
