Who can stop an evil force more powerful than the Justice League? Clairvoyant Madame Xanadu has foreseen that the only means to save the planet from an evil sorcerer is to assemble a group of the world's most powerful and bizarre magical heroes. Not one of them would ever choose to work with the others. And yet, this Justice League of the Dark Arts must succeed where the established Justice League has failed: Take down the evil sorcerer before he gathers The Books of Magic, the four tomes from which all magic flows. These are dark times, indeed.
