Batgirl v03 - Mindfields (2016)

THE BATTLE FOR BURNSIDE IS ON!
She rides a cool motorcycle, swings a mean right hook, and has backup from the best crime-fighters in the biz, but Batgirl's greatest weapon has always been her mind. As the brilliant Barbara Gordon, she's on the verge of a tech breakthrough that could transform her beloved Burnside neighborhood, and all of Gotham City to boot - though if it falls into the wrong hands, it could just as easily devastate them.
But how can Batgirl stop a hacker who can break into her brain itself?
A sinister figure has been haunting Batgirl's nightmares and stealing all her secrets, from her high-tech innovations to her hidden identity. And he'll use that knowledge to destroy her forever.
Now Batgirl must assemble a band of her best friends and closest allies - including Spoiler, Black Canary, Batwing and more - to stop the most dangerous enemy she's ever known, or Burnside and the entire Bat-family will burn...
It all comes down to this! The revolutionary creative team of Cameron Stewart, Brenden Fletcher, and Babs Tarr bring the saga of the Batgirl of Burnside to a close in BATGIRL VOL. 3: MINDFIELDS. Be there for the shocking climax to one of the greatest Batgirl stories ever told!
