DC Comics Bombshells #19

"The Batgirls are back! A mysteriously cloaked shadow calling himself 'The Reaper' is upset at the events that occurred last time with Harvey Dent, and is determined to nip the problem at its roots-Dr. Strange, Killer Frost, and the Penguin! Now, the Batgirls must use their collective detective skills to warn those villains first, before the Reaper gets to them!"
