Vensa Cold-Chart is Ridge-Hold's Chief Cartographer — meticulous, brilliant, and quietly obsessive. For seven years she's been compiling a comprehensive survey of the Northern Compact's maps, and for seven years she's been finding discrepancies. Routes that exist on no terrain. Borders that shifted without treaty. Mining claims that were granted, then erased from the record.

Her mentor noticed the same discrepancies. Five years ago, she was found dead at the bottom of the archives. Officially: an accident.

When Vensa's map analysis leads her to a ruined mining family's lost claim, and the surviving son's investigation into his family's ruin leads him to the archives, their paths collide. The discrepancies and the injustice are connected — woven into a conspiracy that stretches back a hundred years, to a hidden territory that someone has been deliberately erasing from every map in the Compact.

Steward Brevik Gem-Ward has spent three decades protecting the secret. He believes he's preventing a catastrophe. But his protection has come at a cost: revoked claims, falsified records, a dead cartographer, and a community that's been lied to for generations.
