Briar Hollow, Texas was never meant to survive the Snap. When a catastrophic rupture in reality tears through the limestone beneath the Briar Hollow Museum of the Unseen , gravity itself begins to fail. Streets bend. Water rises into the air. Buildings warp as if the land is being rewritten from below. Rowan Cross never asked to lead the fight against something that cannot be killed. Yet when the fracture spreads beyond the museum and into the town itself, he realizes the war has changed. The entity known only as the Thorned Witness is no longer trapped beneath the museum's portal-it is growing through the land. As gravity anomalies spread across Briar Hollow, Rowan, Maeve, Evelyn, and the wounded Clay race to contain the spreading fractures. But the Witness has learned a new strategy: turning the town's own residents into living conduits for its impossible geometry. When a local man becomes possessed during a violent gravity surge near the creek, Rowan and Maeve face an unthinkable choice-destroy the human anchor or allow the fracture to tear the town apart. They choose survival. But the cost is devastating. Because Briar Hollow is no longer the only place breaking. And the Snap was only the beginning.
