The adventures of the World's Finest heroes continues in this new hardcover. First, sidekicks Robin and Supergirl must go undercover in Arkham Asylum. Then, Flash foe Gorilla Grodd strikes at Superman and Batman through their weakest links: their closest confidants, Lois Lane and Alfred. Plus, a spooky Halloween tale delves into what scares Superman and Batman as well as their greatest foes, Lex Luthor and The Joker. And an epic tale tying into DC's BLACKEST NIGHT turns Man-Bat, Bizarro and Solomon Grundy loose on Superman and Batman's hometowns of Metropolis and Gotham City. "From the Hardcover edition."
