Kara Zor-El lives a life of small problems. How are you supposed to hold a floppy little baby like her new cousin Kal? Who should she ask to the spring formal? And when will her father and her uncle Jor-El stop squabbling? But the planet Krypton has big problems... like the militaristic dictator Zod ruthlessly crushing dissent and threatening to unleash the planet's most dangerous weapons on the opposition. And when things boil over and Krypton begins to burn, Kara and her infant cousin will find themselves trapped together in a prototype rocket, struggling to survive in a hostile universe that doesn't care if they live or die... and which might prefer the latter! Breakout writers Ethan Parker and Griffin Sheridan (Eisner Award nominee Kill Your Darlings) join visionary artist Rod Reis (New Mutants) to tell the story of teenage Kara and infant Kal, sent on their journey through the stars together, not apart... that is, as long as Kara can keep him alive!
