Spinning directly out of the events of DC K.O., Batgirl is back in Gotham City when she wakes up with the twisted, metahuman abilities of the Blood--the power to wield and control her blood like a weapon. But her Bat-Family reunion is cut short when she is forced to ascend Wu Corp Tower to confront her Blood relatives for answers and a reversal of this curse. Cassandra Cain has leveled up...or is it a level down? The perfect jumping-on point for new readers of this hit series, as The Curse of the Blood begins here!
