Now, to bring Krypton's killers to justice, Supergirl will have to face down an entire planet of Green Lanterns...including her friends. Her path will take her from a bar for alien criminals to the middle of a civil war in the Vega system.

And--worst of all--it will take her home. To the ruins of Krypton...and an asteroid field of deadly Kryptonite
