"There is light in the Dark Knight's life at last. Bruce Wayne has met a woman who is every bit his match as an intellectual equal, and a survivor who has overcome unspeakable trauma to reach the top of her field. He's ready to share everything with her--even the secrets behind Batman. But elsewhere in Gotham City lurks another masked man who suffered as a child. Yet unlike Batman, this twisted figure wants to make the world pay for what he went through. Through a combination of high technology and mind-warping hallucinogens, he's kidnapping the citizens of Gotham in a sadistic attempt to recreate a wonderland he long ago lost. He is the Mad Hatter. And he's about to draw the Dark Knight down a rabbit hole of terror! Everything hangs in the balance in the Dark Knight's life as Bruce Wayne grapples with revealing Batman to the woman of his dreams. Can the Caped Crusader save the city--and his new love--before the Hatter shatters their world forever?"--Provided by publisher.
