A mysterious new vigilante has taken to the dark skies of Gotham City and quickly makes her formidable presence felt with an awesome array of hi-tech weaponry and martial prowess. And leaves the criminals, the police, and the ordinary citizens wondering: who is the Batwoman?
Not even the Dark Knight knows but her ruthlessness and questionable tactics force him to solve this most enigmatic of mysteries before she inadvertently kills someone.
But the further he investigates the mystery, the stranger it becomes. Is she Kathy Duquesne, the pampered, spoiled daughter of the up and coming crime lord Carlton Duquesne? Or is she the hard boiled police detective Sonia Alcana with an axe to grind against Boss Rupert Thorne? Or does the klutzy techno-nerd and brilliant female scientist Rocky Ballantin hold the answer to the Batwoman's identity? Or do none of them have anything to do with the female bat-themed vigilante at all?
But when it is over, the true secret of the Batwoman will be revealed and the truth will rock the Batman's world.
