Wydrin of Crosshaven, the quick-tempered mercenary known as the Copper Cat, joins brooding knight Sir Sebastian and crippled nobleman Lord Aaron Frith on a dungeon delve that goes catastrophically wrong. Their meddling releases a dormant god-made army of serpent-women, and what began as a gold-chasing job becomes a continent-spanning responsibility. The Black Feather Three, as they come to be known, tumble from one crisis to the next — part heroic, part reckless, always entertaining.

Wydrin is the beating heart of the trilogy: irreverent, loyal to the bone, quick with a blade and quicker with a quip. She is far more emotionally intelligent than she lets on, and her relationships — especially with Sebastian and Frith — drive as much of the plot as the monsters do.

Across three novels the trio battles gods, mages, pirates, and even Wydrin's own notorious pirate mother. Each book deepens the world and the characters while escalating the magical stakes, culminating in a quest to a cursed island that tests loyalty and legacy. Themes of found-family, guilt, and what it means to be a hero underpin the adventure.
