Eight hours of air. An erased mission log. And a dead world that was never dead.
Terraforming engineer Sera Vey wakes aboard a failing research station orbiting Nysa with one urgent problem: life support is collapsing. But when she searches for the cause, she discovers eleven days have vanished from the official record-and every surviving trace points back to her.
Someone wanted those days forgotten.
As oxygen runs out, Sera follows the evidence hidden in damaged machines, buried recordings and her own missing memory. What she uncovers could destroy the terraforming mission, expose the people who erased the truth, and change humanity's claim to Nysa forever.
Because something is alive below the planet's supposedly sterile surface.
And Sera may have already risked everything to protect it.
The Erased Horizon is a tense, immersive science-fiction thriller about survival, memory, corporate power and the terrible cost of turning a living world into a human one.
