The Challengers continue to investigate Darkseid anomalies throughout the universe... and... within themselves...? As more Challs members face isolation aboard the Watchtower and evaluation by Mr. Terrific, a closely guarded theory begins to form as to why the Challengers might have been particularly affected by Darkseid's disappearance... even as they're kept in the dark while the League speculates. Now Red Ryan must investigate a newly sentient asteroid with the Green Lantern himself -- Hal Jordan. But what does it mean when Red can begin to hear the asteroid's... thoughts? And what happens when he loses control of his own body after being exposed to the asteroid's... blood?
