Demon 12 (en Inglés) - Bruce Hennigan

There is no rest for Jonathan Steel! Following the defeat of the thirteenth demon, Vivian Ketrick has plans to take control of its territory. But another-and much more powerful-entity has arrived from Europe to challenge her claim. Rudolph Wulf has genetically engineered his blood to carry "vampire magick,"and he is using it to recruit an army of vampires and werewolves the likes of which the world has never seen.

Raven, an assassin from Steel's past, has also surfaced. Hired by Vivian, she has dark plans of her own and could hold the key to Steel's lost past. As the forces of darkness converge for battle, Steel is caught between his desire to regain his memories and his mission to save the lives of those he cares about most.

Fast-paced and thrilling, The Twelfth Demon, Mark of the Wolf Dragon stretches from the slums of the big city to the shadowy world of Transylvania to explore the legend and lore of vampires.

In "Demon 12: Wolf Dragon", Steel must help Joshua Knight in the aftermath of tragedy and in the process, uncovers a vampire "clan" devoted to Rudolph Wulf, the "12th demon". Josh is soon taken by the clan and Steel follows him to caverns of Transylvania where he must stop a vampire army from being unleashed on the world. This "author's" cut restores the original manuscript of "The 12th Demon: Vampyre Magick".
