After an experimental engine test beneath the Briar Hollow Museum of the Unseen, the town doesn't erupt - it compresses.
Tourists faint inside the gift shop. Birds reverse mid-flight. Residents suffer migraines and unexplained nosebleeds. The air itself thickens as if something vast is pressing inward from beyond sight. When the museum doors lock themselves at dusk and a child sleepwalks toward the basement foundation, Rowan and Maeve realize the disturbance isn't random.
It is responding.
A towering stone entity manifests at the edge of town, so massive that gravity bends around it. Telephone poles tilt. Buildings strain. The sky bows downward under crushing force. Possession spreads strategically - not chaotic, but deliberate - as the Harvester establishes conduits and stabilizes fractures through human hosts.
Engineer Clay discovers something worse than a breach.
A ledger.
"CONTACT ACKNOWLEDGED."
The phenomenon is not invasion. It is integration. Briar Hollow is being mapped, recorded, and reinforced under unimaginable pressure.
Rowan and Maeve survive the first phase - but survival costs blood, stability, and certainty.
The fractures are accelerating.
And the town is no longer merely under threat.
It is under construction.
