Rachel Parker deals in facts, not fear. But when a man collapses at her feet-eyes wild, running from something no one else can see-her world begins to unravel. Because she's seen this before. The night her partner, Elliot, died. A shadow with cold, blue eyes watching from the dark. She told herself it was grief. Stress. Just a trick of the mind. But now the bodies are stacking up, and the shadow... it's back. As the veil between logic and madness begins to tear, Rachel is forced to confront the one thing she's always outrun: fear itself. She joins forces with a fractured group-survivors, skeptics, and those marked by the same gaze-to uncover what the blue-eyed entity truly is... and why its arrival always ends in death. Some say it's a curse. Others, something ancient-something twisted beyond reason. But one truth remains: The more they search for it, the more twisted everything becomes. And it's already watching.
