"After the murder of her father, Supergirl has scoured Earth for his killer - Reactron. But now that all Kryptonians are banned from the planet, she's gone from friend to fugitive overnight. Squad K, a government-run, anti-Kryptonian unit, hunts down trespassers, and it has just recruited Reactron and his gold Kryptonite to stop Supergirl. Even with her target coming at her, Kara's mission couldn't be harder. Her only allies, Flamebird and Nightwing, are convinced that they are Krypton's greatest legends reincarnated, yet they're also America's most wanted. How can Supergirl bring the killer to New Krypton to stand trial, if on Earth he is the hero and she the villain? How far will Supergirl go to deliver justice on a world that no longer believes in it - or her?"--Cover.
