Birds of Prey (Birds of Prey Vol. 5 #18)

When Oracle intercepts chatter about Sin from the ninja clan long bent on acquiring her, Dinah, Sin, and Megaera decide to set a trap instead of waiting for an ambush. Meanwhile, Constantine reaches out to Oracle for last-minute help moving a tricky demon across a dimensional plane, but Oracle only has the skeleton crew of Big Barda and Cass Cain on hand... and they might not be the best fit for this particular mission.
