Redux

The domed city of Evanescence is in ruins. With nowhere to go, prodigy hacker Ellani "Ella" Drexel and a small band of survivors flee to the Undertunnel below their city.
To escape the wasteland she unknowingly created.
But sanctuary is hard to find. With malfunctioning androids and angry rebels at their backs, the group hopes to press on for the neighboring city of Cadence. But Ella's chosen path is challenging...life-threatening, even. Worse, the boy she loves is acting distant, and not at all like the person she first met in Nexis.
But then Ella learns a secret...and it changes everything.
Ella knows she needs to turn back and make a stand to reclaim her home. She's determined to bring a new—and better—life to all who've suffered.
Or die trying.
