Dark desire

The book begins with Jacques Dubrinsky, younger brother to Mikhail, being tortured and buried alive by members of the same fanatical group that attacked Raven and killed his sister some 25 years earlier in Dark Prince. As time go on he loses much of his memory (perhaps even his sanity), the only thing he has a clear memory of is of the faces of his human tormentors, the vampire who betrayed him to the society, and of the woman who will save him.
