Superstar writer Jeph Loeb and the red-hot art team of Ian Churchill & Norm Rapmund join forces to deliver a new monthly series spinning out of the sell-out run in SUPERMAN/BATMAN featuring the adventures of Superman's cousin from Krypton, the one and only Kara Zor-el! Kara's story begins with the same brand of high-flying adventure as she begins her whirlwind tour of the DCU! And the first hero she squares off against is Power Girl! Before this tale guest-starring the JSA is complete, secrets behind the origins of both will be revealed!
