Sella Rooke was born within earshot of the Lordinium dry docks, in a rope-walk tenement where the tide is the only clock anyone trusts. Her mother caulked seams, her father hauled cradle timbers, and by the age of nine Sella could name every ship in the harbour by the sound of her hull being tapped. At seventeen, hungry for a wage that was not a dockhand's, she signed as deckhand onto Carl of the Seven Seas' third northern voyage, because Carl's name was still good coin then and the harbour had not yet learned to count his lost crews.
She was the youngest hand aboard and the strongest for her size, and the bosun took a liking to her, which she later understood was a different kind of arithmetic entirely.
The ship went down in a heavy sea nine years ago, in water the charts said was safe. Sella was below decks when the hull opened, ordered there by the bosun minutes before, and she came up through a hatch into black water and swam to a spar and then to a shingle bar, and she was the only one. The harbour needed a reason. A seventeen-year-old girl who lived was a better reason than a hull that failed, and the gossips of the Tarred Keel settled on her within a fortnight. The harbourmaster's office declined to investigate. Carl, home with his own grief and his own torn map, never learned her name.
She went back to the cradles and stayed. For nine years she has worked the Sea-Devil's Due's sisters, learning copper sheathing the way priests learn scripture, tapping hulls by ear, sleeping in the cooperage loft in bad weather. She earned the name Keelbreaker the honest way, by breaking up a condemned hulk single-handed in a winter gale to free a cradle before the tide took the whole dock, and the dock crews have called her by it ever since, half in respect and half in warning.
Halda Storm is the one thread of the old voyage she never cut. Halda was third mate then, and she was the only officer who said aloud that a deckhand does not sink a ship. Sella has never decided whether that was belief or kindness, and the not-knowing has kept her sharp for nine years. When Carl came home and began hiring for the north, Halda sent for her personally, and Sella signed the letter before she finished reading it, because the Sea-Devil's Due was going north, and north is where her tally's oldest name is waiting.
Her driving goal is simple and enormous: a mate's berth, and the words out loud. Everything else — the Chorus, the fog, the god beneath the island — she will meet the way she meets a hull: by tapping it, listening, and finding where it is cut.
