For long years, Superman thought he was the lone survivor of his lost world.
That all changed the day a spacecraft crashed or Earth- and a young girl emerged from the wreckage.
A Supergirl from Krypton.
And Superman's life would never be the same.
Collected in this volume is the story that launched the Supergirl concept as well as the history and first appearance of Kara Zor-El, the teenager who would become Supergirl. From her escape from Argo, the city that was spared Krypton's doom, to her adoption of the secret identity of Linda Danvers, to her first meeting with Superman, these tales capture the magic of the Silver Age!
