In "To Save a Superman," writer Cary Bates and artist Mike Kaluta deliver a gripping tale set beneath the ruins of Krypton, where a desperate time experiment goes awry. When scientist Mal-Va's assistant Zol-Mar is sent into the past with the hope of altering history, his own ambitions collide with a malfunctioning device—leaving him stranded in a timeline far from his own. Neal Adams' striking cover captures the mystery and tension of a story where the past holds more danger than salvation.
