Escaping the fate of Argo, Krypton's last surviving city, Kara Zora-El is sent to Earth in a rocket to be reunited with her long-lost cousin, Superman. Under the Man of Steel's guidance, Kara is trained to become one of Earth's greatest heroes! So begins SUPERGIRL ARCHIVES Volume 1, a 228-page hardcover written by Jerry Siegel and Otto Binder, with art by Jim Mooney and Al Plastino and an all-new cover by Frank Miller! Volume 1 showcases the origin and first appearances of the Girl of Steel, reprinting not only the classic Supergirl stories from ACTION COMICS #252-268, but also the time Superman encountered a prototype Supergirl from SUPERMAN #123, which preceded ACTION COMICS #252 by eight months! These early adventures of Supergirl show her adopting the secret identity of Linda Danvers and performing her super-heroic actions while hidden away from society, giving her the status of Superman's Secret Weapon. Supergirl inevitably becomes a public figure, breaking the bonds of the 20th century to fight alongside the Legion of Super-Heroes and Tommy Tomorrow! And let's not forget her adventures with Streaky, the Super-Cat! Featuring an introduction by Dark Horse Comics editor Diana Schutz, SUPERGIRL ARCHIVES Volume 1 is chock-full of charming stories that return us to simpler times, as a 15-year-old girl learns to fly and becomes one of history's greatest heroes!
