The Archivist of the Abyss

Barnaby is a junior archivist in the Great Submerged Library - a vast underwater institution where octopus scholars preserve the fading records of a drowned civilisation. His work is painstaking, solitary, and precisely ordered: transcribing dying pigments from salvaged membranes, cataloguing the bureaucratic remnants of ships and treaties and taxes. He is good at it. He does not ask what the records mean.
He copies what is there. Then a route appears under his skin. A map, surfacing unbidden in the chromatic layer of his own body - a navigational line pointing beyond the edge of charted territory into waters the Library's official record does not acknowledge. When Barnaby follows it, he discovers what the institution has been hiding: a network of erased routes, a prison hulk sunk in deep water, and the testimonies of people who were disappeared and classified as weather.
The archive that should have preserved their names was used instead to erase them - and the evidence of that erasure has been encoded, by dissident hands, into Barnaby's own flesh. With Mira, a fierce independent cartographer who has spent years tracing the same conspiracy from outside the institution, and Coil, a harbour salvager haunted by what he found and chose not to report, Barnaby must decide what to do with a truth his body is already telling - whether to let the Library contain it, or to release the names of the dead into the world before the institution can bury them again.
The Archivist of the Abyss is a literary fantasy about archives and accountability, institutional power and the persistence of testimony, set in a fully realised underwater world where the politics of memory are as pressurised as the ocean itself. It is a novel about what happens when a quiet, careful person discovers that the system they serve has been lying - and that the evidence is written on their body.
