Deadspeak

The silence of the grave is not silent at all. In their millions, the dead are screaming...but no one can hear them!
Atop a perilous cliff, deep in the Balkan mountains, rises the castle of the Ferenczy. Once it was a stronghold of the Vamphyri...and now it will be so again, for Janos Ferenczy, vampire and black magician, has risen from his ages-long sleep. Powerful and evil, Janos conjures dead men and women into a semblance of life and subjects them to fiendish tortures.
But the shrieks of the dead do not satisfy Janos's lust for blood, for that he needs living humans. His terrifying armies of the risen dead will soon overwhelm a helpless, defenseless mankind...
Helpless and defenseless because a terrible battle against the vampires has destroyed Harry Keogh's deadspeak, leaving the Necroscope deaf to the teeming dead...and to their warnings of Janos's reign of terror.
To save the world, Harry must join forces and link minds with the most powerful, and deadliest, vampire of all!
