Outnumbered and outmaneuvered, all that remains of human civilization is teetering on the brink of extinction once again. In the aftermath of another viral crisis, a tenuous truce between the Fusion and human colonies appears set to ensure the safe expansion of Amaranthe into the newly established Leonine District ... but not everything is as it seems. The genetic barrier between human and Fusion seems to be dissolving right before the eyes of Silver and Alex, and time is quickly running out. While they're under pressure to halt the progression of the Fusion conversion before it takes hold, the arrival of a mysterious group of emissaries offering freedom and security to the city proves to be a tempting distraction. That is, until Silver discovers that they're not just bringing their expertise and resources—they're bringing the dawn of a new age.
