The Christian novels for teens by Bill Myers entitled Forbidden Doors deals with the occult in a humorous and engaging way. There are multiple novels with numerous plot twists and turns that keep it interesting. Forbidden Doors is one of the best resources I have seen that helps fight against the onslaught of the occult directed at youth.
