Unseen by an apathetic society, a stupendous battle is being waged between good and evil. In the center of an unassuming town, gathered in a nondescript hotel, are the most powerful forces of time eternal: the thirteen black covens. On All Hallow's Eve they unite to summon the Black Magician, the darkest and deadliest being of all time.
They are a rag-tag group of misfits: an inexperienced but lovely witch, an ancient sorcerer obsessed with math, and a private detective who can't seem to solve a case, but they are humanity's only hope. The world is unaware of the battle, but it will suffer the ultimate consequence if the war is won by the black evil.
Can a group of social rejects save the world? Or will humanity plunge forever into the abyss?
