"Dinah Lance is one of the DC Universe's most elite fighters, and combined with her sonic scream, she's a fearsome foe in any scenario...but sometimes even the Black Canary needs help. Faced with a personal mission brought to her by a mysterious new ally, and up against near-impossible odds, she re-forms the Birds of Prey with an unrivaled group of badasses-Cassandra Cain, Big Barda, Zealot, and Harley Quinn-and only one goal: extraction without bloodshed. What could possibly go wrong?"-- Provided by publisher.
