For decades, Sterling Associates has managed the silence of Greyback Mountain. But when the North Face begins to shrug, the managed history of Briarhollow starts to crack. Nora Thorn, the town's newly appointed archivist, finds herself trapped between a federal disaster team and the mountain's own geological scream.

As she deciphers the "Lily Paradox" and recovers the lost logs of 1962, Nora realizes that the town's survival isn't a matter of engineering, but of archival integrity. The mountain is a geode of secrets, and the only way to stop the collapse is to expose the foundation of lies that holds it together.

In the final volume of the Briarhollow trilogy, Nora Thorn must sign the ultimate audit?a signature that will either save the town or bury it forever.
