In Briar Hollow, Texas, the creek does not rise without reason.
After a flash flood slams into the Museum of the Unseen, Rowan Cross and Maeve Alvarez discover a waterlogged trunk lodged behind the building-stamped with the museum's logo from decades ago. Inside is a warped page from Rowan's mother's hidden journal, proof that she scattered warnings across time before she disappeared.
Then the drowned return.
A tourist who visited the museum the day before rises from the creek wearing a bright yellow wristband dated yesterday. The body speaks in layered voices. It urges Rowan to "pull" at time-just once-to undo what the flood has taken.
But eighteen years earlier, Clay tried the same thing.
He pulled too hard.
Now the museum hums with fractures no one else can see. Mirrors lag. Reflections misbehave. A hallway forms where no hallway should exist.
The Harvester is no longer testing the edges of reality.
It is learning the shape of Rowan's choices.
And in Briar Hollow, what comes back from the water isn't alive.
It's aware.
