Koriand’r has left Earth on a journey through the stars to search for her sister, who went missing in the aftermath of the Invasion of the Fourth World, and maybe find herself along the way. She does manage to find Komand’r, but also finds trouble: Lady Styx, an eldritch horror hell-bent on decimating every planet she finds. The two sisters have to work together, with help from Adam Strange and the Green Lantern Ch’p, to prevent her path of destruction.
