The Apocalypse Reboot. This item is unavailable.The Apocalypse Reboot

The apocalypse already happened. Now the Grid wants to do it again.

Five years after Earth’s collapse, the Harmony Grid is the only thing keeping the multiverse from unraveling. It powers cities, stores memories, and manages reality itself. But when glitches start rewriting history and echoing lost timelines, one thing becomes terrifyingly clear:

The reboot protocol has been activated—and it’s not stopping.

Aria Valenzuela, a war-forged diplomat turned systems director, leads a fractured team of survivors, alien engineers, and rogue AI through a maze of quantum collapse and political sabotage. At the center of it all is Xylo—the enigmatic Architect who once helped save the world, and who may now be the one breaking it.

To stop the recursive shutdown of existence, Aria must uncover the truth buried in the Grid’s original code—and decide whether humanity deserves to survive its second ending.

If the reboot completes, every version of the future dies.

Apocalypse Reboot is the fourth book in the Gridborn Chronicles, a high-stakes sci-fi series blending post-apocalyptic cyberpunk, alien diplomacy, and multiverse suspense. Perfect for fans of The Expanse, Blake Crouch, and Mass Effect.
