She awakens in a sinking metal tomb, her only memory the taste of oil and dead ocean. With no name and no past, she discovers she is Blake, a "Curator" possessing lethal combat skills she can't remember learning.

Trapped at the bottom of the Zenith Tower—humanity's last vertical city—Blake must fight to survive in a decaying, stratified world. From the flooded "Sump," where memories are a traded drug, to the artificial paradise of the elite's "Verdant Tiers," she uncovers a horrifying truth: she is the Architect, Stella Blake, the creator of the oppressive "Phantom" system that enslaves the tower.

Hunted by the very regime she engineered and haunted by the ghosts of those she sacrificed, Stella faces an impossible choice: reclaim the power of the Architect to "optimize" the world once more, or destroy her entire legacy to give humanity its freedom back.

For fans of the dark cyberpunk of Blade Runner, the claustrophobic dystopia of Altered Carbon, and gritty survival action, Echo Spire is a deep dive into the nature of memory, sin, and redemption.
