JSA: Book 1 : Ragnarock — Paul Kupperberg

In a story that spans the generations, the Justice Society of America (JSA) and the Injustice Society battle in typical superheroic fashion, except that the catalyst for the rise in criminal movement is the Spear of Destiny -- the mythical weapon said to have pierced the side of Christ. From the dark days of World War II through the modern age, the heroes of the JSA -- Hawkman, Hourman, Hawkgirl, the Atom, Green Lantern, Thunderbolt, Mr. Terrific, Wildcat, Dr. Fate, and the others -- have faced countless magical foes. But with the Spear in his hands, the Wizard is much more than just a costumed thug. The fate of the world is at stake, and even the most powerful hero isn't enough to stop the destruction.
