Superman: World of New Krypton (Superman: World of New Krypton #4)

A new planet suddenly appearing in any space sector would demand the scrutiny of the Green Lantern Corps. When the planet in question is New Krypton and the space sector is 2814, it means Kandor City gets a visit from Hal Jordan and John Stewart, with Daxamite Sodam Yat along for good measure. But what starts as a good-will mission soon becomes a manhunt for some of the Phantom Zone's most deranged and dangerous criminals and leads ultimately to dire conflict between the Corps and Zod's Military Guild - with Superman caught in the middle!
