The Last Son of Krypton is about to meet his home planet's nemesis. A remorseless killer called Rogol Zaar has arrived on Earth, bringing wide-scale death and destruction in his wake. Only Superman and his cousin, Supergirl, stand between Zaar and the completion of his mission--the complete annihilation of the Kryptonian race. But even as Kal-El and Kara struggle to contain this new existential threat, the Man of Tomorrow faces a completely different challenge in his adopted home city of Metropolis, where Clark Kent still lives and works--but without his wife and son. The stage is set for a reckoning like nothing Superman has ever faced--and everything that matters to the Man of Steel hangs in the balance!
