Caleb the Undead, the most powerful of all the vampires, was destroyed centuries ago in the Holy Land by a cult armed with spells, silver and stakes of whitethorn. Caleb's disciples, the Vampire Celebrants, have been searching ever since for his last remains, the Unholy Relic, and they intend to use it to resurrect their master and bring order to the world. A vampire order driven by blood, by lust and by revenge. 'Cold Runs the Blood' is Doctor Who writer Elliot Thorpe's first novel and is set in medieval Wallachia, a rich source of gothic horror.
