Justice Society of America, Vol. 3 – Issue 27

Sensing a threat, Obsidian has locked down JSA Headquarters. Everyone but Green Lantern, Wildcat, Flash and Liberty Belle was forced out, and he isn’t letting anyone past a shield of blackness. But his failure to communicate with his teammates leaves them concerned as to his motivations. But everyone’s so distracted by Obsidian’s behavior that they fail to notice when a ghost takes possession of Stargirl, and uses her to force Obsidian back and gain access to the building. A ghost from the Justice Society’s past has returned to avenge itself on the heroes for failing to stop the atomic bomb from being used on Japan.
