In "Princes of Darkness," an insane Alan Scott and the evil wizard Mordru plunge the world into darkness, civil war, and chaos, and the Crimson Avenger wreaks havoc on all those she perceives to be sinners. Then, Black Adam brings old-world justice to Kahndaq as Hawkman seizes control of the JSA and brings them to the turbulent Middle East for an epic battle in "Black Reign"! JSA by Geoff Johns Book Five collects JSA #46-58 and Hawkman #23-25.
