"In this fourth volume of Byrne’s landmark Superman saga, the Last Son of Krypton teams up with the sci-fi schemes of Lex Luthor, and romances the Amazon Warrior herself, Wonder Woman! Then everything changes--again--when a strange new Supergirl arrives in Metropolis. She, too, is a voyager from a doomed world --and when Superman confronts the Kryptonian arch-criminals responsible for its destruction, he makes a decision that will shock readers to the core!"--Page four of cover.
