Deamhan have survived by remaining hidden in the shadows. Ramanga, Lamia, Metusba, and Lugat have been overshadowed by what humans know as the modern vampire. But what if vampires aren't the real threat?

She gains the trust of the only other human familiar with the Deamhan lifestyle. With his help she finds not only can the Deamhan not be trusted but it s her own father, president of a ruthless organization of researchers, who has diabolically maintained that distrust.
