From the Secret Files of the Red Room

Derek Hawthorne was born to be an agent of the Red Room. Literally. Raised in a conspiracy which has protected the world from the supernatural for centuries, he's never been anything other than a servant of their agenda. Times are changing, though, and it may not be long before their existence is exposed. When a routine mission uncovers the latest plan of the magical terrorist, the Wazir, Derek finds himself saddled with a new partner. Who is the mysterious but deadly Shannon O'Reilly? What is her agenda?

Derek Hawthorne has ascended to become a member of the all-powerful Committee, which rules the world through the nebulous House. The House, officially, exists to protect humanity from the vampires, demons, and other forces of darkness that imperil humanity. Unofficially, it exists to protect its own power. 

Derek Hawthorne has slain Dracula and stopped the malevolent plan of his own employers, the sinister House. However, he has discovered that his ex-partner and lover Ashley Morgan has been kidnapped while a new conspiracy moves to expose the supernatural to the world. The House has overplayed its hand and all of its enemies are coming to bring it down. Derek will have to travel dimensions, fight monsters, and call in every favor he's accumulated just to survive.
