A storm tears open an old kirk on the North Sea, and the ground spits up bones that were never meant to see daylight again.
Elspeth MacBride, an Edinburgh scholar with a reputation to rebuild and grief she refuses to name, comes to the coastal hamlet of Dunmoore to verify an impossible claim: the unearthed skeleton of Dubhghall, the Black King, buried in shame and marked by a crown-shaped wound.
