The last adventure of Batgirl Barbara Gordon before the horrific events of BATMAN: THE KILLING JOKE! Batgirl's final case as she goes after Cormorant, the man who "killed" her once. But is it a case of justice, or an obsessive desire for revenge?

Barbara Gordon is no stranger to secrets. She's the daughter of GCPD Jim Gordon, the vigilante known as Batgirl and was once Oracle, the most powerful hacker on the planet.
