The Aldine Key

Wren Callahan has spent her life measuring coastlines for the Aldine Guild, never suspecting that her own mother's survey ledger holds the map to a secret worth killing for. When the ledger falls into her hands, stained with brine, bound in leather that remembers every voyage, she becomes the most hunted cartographer in Loomholt. The Brass Magistrate commands the city from his counting house of mirrors. The Hooded Pursuer walks the fog-haunted quays with ink-black hands and no face beneath his cowl. And somewhere beneath the channel bell, something vast and patient is waiting to be remembered back into the world. Wren's only allies are Cael Marsh, a disgraced guildsman whose daughter haunts his every regret, and Tilly, whose disguises run deeper than any mask. But the ledger will not yield its secrets to logic alone. It requires a key, and the key requires a sacrifice. To save her mother's legacy from the Guild Fleet's burning ledgers and the Ink-Hand's silencing touch, Wren must descend into the drowned archives where the Leviathan Librarian keeps its choir of the forgotten. She will learn that her mother did not merely map the Aldine coast, she mapped the edges of a god. And now that god is waking. The Aldine Key unlocks one choice: surrender the map and let the guild bury the truth forever, or turn the key and risk unleashing a drowned sovereign upon a world that has forgotten how to drown.
