Backed into a corner. Hunted across ruined lands. The war for humanity is no longer a battle of survival—it’s a race against transformation. Ace Holloway never asked to become the Riftborn. But after the fall of Ark 7 and the loss of nearly everything he holds dear, he’s done running. With the Legion's mechanized forces pushing the planet to the brink, and twisted hybrids rising from the corpses of the captured, Jace and the remnants of the Forsaken Order must confront an impossible truth: hiding won't save them anymore.

When whispers of a forbidden pre-Rift weapon—the Nova Shard—lead them to an abandoned research facility, Jace must make an unthinkable choice. To stop the Legion, he must merge his already unstable Riftborn DNA with a device that has previously torn its users apart, mind and body. What emerges is something more than human. And possibly less.

As Rift storms rip the sky and Legion conversion centers turn humanity into machines, the last hope lies in a suicide mission to Bastion City—a resistance stronghold under siege, and the key to finding the Legion’s central intelligence: Prime Unit X-00. But the closer Jace gets to the heart of the Legion, the more he questions whether he’s still fighting for humanity—or becoming something that can no longer claim it.

Fans of The Maze Runner, Attack on Titan, and Horizon Zero Dawn will be captivated by the third entry in this epic 10-book saga—a relentless fusion of sci-fi horror, emotional depth, and explosive action.
