Nicholas Faraday is a scientist, not a soldier, so when a spell gone wrong transports him to a magical world full of demons and the undead, he'll have nothing but his wits to help him survive. After meeting a beautiful yet deceitful sorceress, Nick finds he can alter the very fabric of this world, which he'll need to use every bit of to find a way home. Finding more allies in a strong female warrior, a gorgeous farm girl, and a cunning succubus, Nick will need all his knowledge of biology, chemistry, and physics in order to stay one step ahead of the terrifying Dullahan doing everything it can to force Nick to stay . . . in a grave. *Warning* This adventure contains adult situations, graphic violence, and super cool science.
