A recluse boy born covered in feathers must help his first-ever friend, a young girl named Bianca, as she tries to return to her home beyond the slums of the Maze. They must dodge street gangs and child-snatchers along the way, and perhaps together will learn the secrets to his mysterious past.
Feeling alone and betrayed by Bianca and Gabriel, Poe finds a humbled and apologetic Z, who tells him that all the Mice have been taken by the Scarf Man.
