"Superstar artist Jim Lee returns to the Dark Knight with this premiere issue! The impossible has happened and Batman is on the verge of being taken down by an enemy he cannot defeat: a virus for which there is no cure! And the only hope for his salvation is The Joker! Who infected Batman, what does the Clown Prince of Crime know, and how will the Dark Knight get that information? Together, the enemies crisscross Europe, desperate to find answers before time runs out. Co-conceived by Matteo Casali and Brian Azzarello, this 4-issue miniseries event will feature art by top talents over layouts by the incomparable Giuseppe Camuncoli (HELLBLAZER, Dark Wolverine), with the first issue pencilled and inked by none other than Jim Lee!"
