Teenager Kara Zor-El was rocketed to Earth from the dying planet Krypton. Faced with an entire world completely unrecognizable from the one she grew up in, she’s the ultimate new girl in school—with a planet-splitting right hook. The Girl of Steel possesses all of Superman’s powers, from superhuman strength, speed and invulnerability all the way down to his flight and enhanced senses. Though she struggles to find her identity, she’ll find non-stop action as she fights for justice on Earth and among the stars.
