Batgirl and the Birds of Prey (2016-) #1

"Who Is Oracle?" part one! Someone has stolen the name Oracle right out of Barbara Gordon's past! Hot on this false Oracle's trail, Batgirl, Black Canary, and Huntress are all tracking the same mafia capo…so it makes sense to team up, right? Problem is, Barbara and Dinah need the secrets locked up in Oracle's brain…and Helena Bertinelli would rather put a crossbow bolt right through it!
