The Tidebound Archive edition sharpens the series frame around Ilion's map rooms, vanished shores, and the political bargain hidden beneath the harbor. Mara Venn's investigation now leans further into archival suspense, coastal folklore, and the cost of recovering histories that powerful families paid to erase. As each exposed shoreline returns a different debt, the series follows the fragile line between restoration and revenge. The updated premise emphasizes Mara's inheritance, the tidal courts, and the question that drives the archive: if a map can make a place disappear, who is responsible when the sea brings it back?
