When gods are confronted by problems they can’t solve alone, they call upon mortals with supernatural abilities, called Aigis, to step in. Seventeen-year-old Roxie Lohr has always wondered why her eyes glow different colors whenever she feels intense emotion. Aerigo, a captivating Aigis, not only gives her the answer but also whisks her away into a host of new problems. Suddenly, Roxie finds herself thrust into exotic worlds, an unexpected romance, and a conflict between gods in which only they can decide the outcome…

With the last two Aigis out of the way, Nexus' war can begin. Aerigo's entire life has been building towards a confrontation with Nexus, and he's managed to avoid it, until now. If he's to stand a chance, he must face the demons of his past and unlock the power that can defeat a god. While he battles with himself, Roxie fights for her life against an enemy attacking her mind and body, a fight she must win alone. Baku's divine family is in ruins. His wife is lost to him and his son has become a monster. It's uncertain if Nexus can be saved, or if he's been tainted beyond redemption by an outside source. As the armies of hundreds of gods gather on Nexus' realm, time is running out.

The confrontation with Nexus goes horribly wrong and Roxie is stranded in the Realm of the Dead. After losing so much, she must find a reason to go on and stop the prophecy from being fulfilled. Nexus’s divine parents try to persuade their son to call off the prophecy, for they don’t want to lose their only child. Their attempts fail when the one pulling his strings interrupts. To stop a prophecy from tearing apart the universe, both Roxie and Nexus must sacrifice what they most desire.

First Sergeant Jade Waters and her squad are deployed to investigate the remains of Furya years after the Necromonger Invasion that destroyed the planet. Drawn by dark rumors, Waters is determined to root out the truth; any and all knowledge is vital against the inevitable day the Necromongers reach Earth.
