The Copper Promise
Note! This novel was originally published in four parts: Ghosts of the Citadel, Children of the Fog, Prince of Wounds and Upon the Ashen Blade.
There are some far-fetched rumours about the caverns beneath the Citadel...
Some say the mages left their most dangerous secrets hidden there; others, that great riches are hidden there; even that gods have been imprisoned in its darkest depths.
For Lord Frith, the caverns hold the key to his vengeance. Against all the odds, he has survived torture and lived to see his home and his family taken from him... and now someone is going to pay. For Wydrin of Crosshaven and her faithful companion, Sir Sebastian Caverson, a quest to the Citadel looks like just another job. There’s the promise of gold and adventure. Who knows, they might even have a decent tale or two once they’re done.
But sometimes there is truth in rumour.
Soon this reckless trio will be the last line of defence against a hungry, restless terror that wants to tear the world apart. And they’re not even getting paid.

Jen Williams
Jen Williams crafts fantasy worlds that shimmer with danger and charm, where the echoes of forgotten legends meet sharp wit and complex characters. Growing up in southeast London, she was drawn to dark folklore and fairy tales that whispered of shadowy magic and fierce survival. This early fascination shaped her voice—one that blends the raw edges of adventure with moments of sly humor and emotional depth.
Her debut, The Copper Cat Trilogy, introduced readers to a world where swordplay and sorcery collide with a refreshing irreverence, centered on Wydrin, a mercenary who breaks the mold of typical fantasy heroes. But it was with The Winnowing Flame Trilogy that her reputation truly solidified. Beginning with The Ninth Rain, the series weaves together elements of fantasy and sci-fi with a brooding atmosphere and richly layered storytelling that earned critical acclaim, including multiple British Fantasy Awards. Themes of decay and renewal thread through her work, inviting readers to explore worlds on the edge—where ancient powers stir and unlikely heroes rise.
