We all know that billionaire Bruce Wayne is secretly Gotham City’s vigilante detective and protector, The Batman—but what road led him there? Find out in The Batman: The Deluxe Junior Novel—Special Edition, which includes the exciting prequel story of Bruce Wayne's early adventures on his way to becoming The Batman, as well how those events come to an exciting conclusion in the new action-packed feature film, starring Robert Pattinson as Batman and Zoë Kravitz as Catwoman.
