When coral continents begin to slip beneath blackened waves and the reef-voices fall silent, tideweaver Kaelin Mer must dive beyond the Sleeping Deep to reclaim the first stanza of the World-Song. Armed with a broken heirloom lute and joined by a crew of washed-ashore runaways, Kaelin faces drowned gods, ancient leviathans, and the painful truth that the reef remembers what the world tries to forget. A story of elemental wonder, loyalty, and a world crying out to be saved.
