The sea has always taken an island. This time, it is moving before anyone has named one.
Maren Vask trusts gauges, records, and clean measurements-especially when frightened islanders would rather believe in rain, wind, or anything but disaster. But the tide is rising too soon around Ilsmoor, swallowing drowned roads and climbing past marks that have held for generations. If the reading is true, her home may be facing its fate ahead of schedule. If she stays silent, the islands lose the precious time they have left.
Every generation, the Compact House chooses which island the sea reclaims. This generation's bargain places Maren beside the one person she cannot agree with on anything: a rival whose decisions could save her people or condemn them. Forced into proximity by old rules and new danger, they must navigate court intrigue, island loyalties, and a bargain neither can make alone. As saltwater closes around their world, Maren must decide what she is willing to sacrifice-and whether trust can take root between enemies before the sea demands its due.
