In the aftermath of Superman’s epic Warworld Revolution, the Man of Steel is back on Earth and stronger than he’s ever been! As he and Steel join forces to remake Metropolis as a true City of Tomorrow, two of Superman’s classic villains take notice…and they have plans of their own. Plus, Kal-El reunites with the Dark Knight, Jimmy Olsen, and the Justice League to find out what he missed while he was away. And Jon Kent’s relief at his father being back is short-lived when he’s targeted by the mysterious Red Sin, who can do the unthinkable: injure both Jon and his father! This volume collects Superman: Son of Kal-El #16-18, Action Comics #1047-1049, and Superman: Kal-El Returns Special #1!
