Superman action comics

"Vandal Savage has had millennia to plot a way to draw back to Earth the comet that granted him powers of immortality, and now he finally has his chance. And it just might spell the end for Superman. Savage's plan hinges on draining the Man of Steel of his abilities, leaving him literally powerless against Savage and the army of his descendants being driven into a frenzy as the comet approaches. When the Justice League and a depowered Superman all fail to halt the immortal's plot, the only way to stop him is with the one element that has the power to kill the Last Son of Krypton for good. Even if Superman is able to save Earth from Vandal Savage, will he survive the attempt? Or will the Man of Steel be forced to make the ultimate sacrifice?"--
