The Great Hush

To stop the rising, Edda must go down: past the Toploam, past the Deeploam, into the deepest dark, where the fog is made of half-erased faces and time itself runs thin.

What waits at the bottom is the Great Hush, the oldest and heaviest thing the world ever chose to forget, and the answer to the question Edda has carried since the beginning: who she is, and why an order that should have buried her long ago has let her live. The truth is down there. So is being Unmade. And the only way back up may be a trade she has watched destroy everyone who ever made it. The series has been going down for five books. This is the bottom.
