Eclipso, the original spirit of vengeance, needs a new human host. The Spectre, the current spirit of vengeance, has just lost its human host and is vulnerable. When Eclipso seeks a new body, it first tries to control the most powerful soul on Earth - Superman. It takes the World"s Mightiest Mortal, Captain Marvel, to stop him…but not for long. Inhabiting the body of a familiar, tortured soul, Eclipso sets its sights on seducing the Spectre, and destroying Earth"s practitioners of magic. Seven heroes stand in their way. All very different. All with different goals at stake. And an eighth is found - who might be the most powerful teenager in the universe. Is even the Shadowpact, aided once more by Captain Marvel, enough to stop these angry spirits?
