Revealed By Shadows

Kaleb, Chaz, and Daniel Stevens are just trying to live normal lives, but when they discover that a ritual to end God’s presence on Earth is going to be performed, they step in to prevent it - being vampires, they’re better suited than the Police, and despite certain biological requirements, they genuinely like people; it’d be a shame for the world to be annexed into Hell like that.
Aided by their human friend and budding witch Rana, and a helping hand from the minor demon calling itself Dom, they are pitted against the power-hungry sorceress Lillian Ferenczany and the life-leeching Dr. Elias Zachary and his zombies, the vampiric Corporate mogul, Darius, and their own problems. Rana and Daniel have been attracted to each other, but too scared to ruin their friendship to do anything about it, Chaz gives in to his thirst and goes on a wee killing spree with a werewolf acquaintance, and Kaleb has to deal with a woman he’s sired. When has a crisis ever waited until life was uneventful to strike?
