As Killer Moth descends on Gotham once again, this time having been given a mysterious "offer" of power by Lex Luthor, Batgirl has her hands full. But before she can even begin to exterminate the villain's plans, she's confronted with an even greater powerhouse of evil--the Terrible Trio, now joined by her own rogue creation, Oracle! When her spinal injury kept her from working as Batgirl, Barbara provided intel to Gotham's heroes as Oracle, aided by an artificial intelligence she devised. Now that abandoned A.I. has been rebooted--and is willing to set Burnside ablaze to confront the creator who left her. But how can Batgirl outsmart a villain who already knows her every move? Plus, Babs's new favorite book series--an epic-fantasy page-turner called Unearth--blurs the line between fiction and reality!
