Something is opening in Briar Hollow, Texas.
At first, the fractures appear as impossible events-gravity turning sideways, animals fleeing forests in silent waves, and the sky splitting open for seconds at a time before sealing itself again. But Rowan and Maeve soon discover the truth is far worse than a natural disaster.
It is an invitation.
A secret society calling itself The Society of the Threshold has begun gathering outside the Briar Hollow Museum of the Unseen. Their leader claims humanity is evolving and that the fractures are gateways to a higher state of existence. Those who align with the mysterious force behind the distortions gain impossible protection-surviving gravitational warping and otherworldly energies that should kill them instantly.
But Rowan, Maeve, and their allies know the truth: the entity behind the fractures is not offering transcendence.
It is harvesting consent.
As cult numbers grow and the sky itself begins to crack open, Rowan must dismantle the Society before the Witness fully crosses into our world. Yet every act of resistance only seems to strengthen the cult's resolve.
Civilization trembles.
Reality bends.
And the threshold between worlds is beginning to open.
