Batgirl
"Gotham City can be dangerous. No one knows this more than Barbara Gordon. Recovered physically but not emotionally, Batgirl is back on patrol. Unfortunately, others have their own ideas about how best to safeguard the city. These vigilantes will execute every criminal they find, down to the pettiest offenders. The answer to a maniac named Knightfall, a masked woman who wants to save Gotham, but not before drowning it in blood. Smart and skilled, she is every bit Batgirl's equal. But right now, Batgirl isn't who she used to be" -- dust jacket flap.
