IT'S A LONG WAY DOWN! Green Arrow has been thrown from a skyscraper and is tumbling toward the pavement at terminal velocity. His would-be killer: an enigmatic teenage girl with connections to a secretive Gotham family—and a connection to Batman, Green Arrow, and Black Canary's past. Will Gotham's new Dynamic Trio be able to track down this strange, homicidal girl known only as Arabella? Will they be able to unravel the mystery of her past's connection to their own? And, more urgently, how on earth will Green Arrow survive a 70-story fall?! The answers lie in this can't-miss issue!
