What she stole

Dace Marigold has never met a lock she couldn’t open or a debt she wouldn’t pay.

So when a stranger offers enough to buy her sister out of the court’s labour camps, she dives nine marks beneath the Lantern Sea and steals a key of glass from the Warden’s own vault.

The Key bites. It drinks her blood, closes round her finger like a ring, and will not come off her alive.

Lord Leander Orme, Warden of the Ninth Fathom, is sworn to take it back. His voice can make anyone obey, so no one has ever told him no and meant it.

Until her.

Bound together by the Key, they go down into the deep, towards a court that wants what is on her hand before the Kindling: the one night each year that keeps the Glass Sun burning.

The light is failing. And the only man who cannot lie to her is the one sworn to take it from her.

The opening pages

Chapter One Dace

The dropstone was a slab of slate the size of a breadboard, with a hole bored through one corner and a long coil of tarred line knotted through the hole. I had borrowed it without asking from Old Tenacity, who like everyone in Wrackhold is named for the wreck he was born on. In Wrackhold, taking without asking is called borrowing until the owner notices. After that it is called a debt.

I sat on the rail of the Sorry Annie, a dead hulk at the edge of town, with my feet in the Lantern Sea and the other end of the line tied to her bitts, and breathed up. Slow in, slower out. Boys on the wrecks breathe fast before a dive because it makes them feel brave, and it does, right up until it makes them dead. Fast breathing hides the warning. You feel fine all the way down and fine all the way up. Then somebody fishes you out with a boathook.

Content notes

Sexual content (one open-door scene); captivity and binding; violence and on-page death; drowning and near-drowning; blood magic; forced labour, referenced rather than shown.

The Caul

Beneath a dying glass sun, every light has a price.

The Caul is a world inside a cave the size of a sky, lit by the Glass Sun: a ball of fire and glass that no one living can explain, and that is slowly going out.

Each year its peoples pay the Sun a share of their magic to keep it burning: the deep court of the Fathoms beneath the Lantern Sea, the winged Gyre of the high winds, the iron Anvil, the poisoned houses of the Hanging Wood.

Nobody asks what the Sun is. Nobody asks what it costs.

Then a thief steals the key to it.

The Glass Sun Saga

Ten books, each with a romance of its own. Books One to Three follow Dace and Leander. Later books follow new couples from across the Caul, as the truth about the Sun comes closer to the surface.

Aurelia Ashcombe

Aurelia Ashcombe writes slow-burn romantasy for readers who like their heroines sharp, their heroes dangerous, and their love stories earned. Her books are full of thieves and oaths, dark water and old debts, and men who fall first, fall hard, and would sooner burn than let her go.

She lives on a small island in the Mediterranean, where the sea is never far from the window or the page.

A Key of Salt and Glass is her debut and the first book of the Glass Sun Saga.
