In the crucible of progress, sacrifices must be made. The weak must fall to make room for the strong.

Haunted by the devastating loss of Chris, Liz finds solace waging a solitary war against the oppressive government. Driven by vengeance and consumed by grief, she unleashes her formidable powers against the regime that stole everything from her. But even a girl with wings and superhuman abilities has her limits, and as Liz's reckless pursuit of justice escalates, she unwittingly sets the stage for a reckoning.

As Liz battles her personal demons, a greater threat looms-the insidious spread of the Chead. Guided by the ancient and enigmatic Talisa, these creatures ravage the land, leaving towns in ruins and slaughter in their wake. Their merciless rampage spares only the young, consigning them to a fate that will transform them into Chead themselves. In a world teetering on the edge, the tyrannical government might just be humanity's last hope.

In this heart-pounding conclusion to the Evolution Gene trilogy, the forces of good and evil collide, pushing the indomitable spirit of humanity to the brink. As alliances are forged and shattered, and the line between enemy and ally blurs, it all comes down to one choice.

Will Liz's thirst for revenge lead to redemption, or will the world fall?
