A young woman from a kingdom locked in time by a demon king's curse stumbles into the forbidden wood and is taken captive by Nyfain, the golden dragon prince who alone keeps the cursed realm from collapsing. She learns she has the rare ability to help break the curse — but doing so means giving herself to the monstrous, tormented prince who is as much danger as salvation. The series begins as a dark Beauty and the Beast retelling and expands to encompass the demon king, the fae, and a shifting world of magical politics.

Finley, the heroine of the first four books, is resourceful, botanically brilliant, and defiantly independent — a working-class woman who refuses to be diminished by a world that underestimates her. She is a 'strong female lead' in the most grounded sense: her strength is practical and emotional rather than magical, and her growth into a queen feels genuinely earned. Aurelia in the duet is similarly resilient but more wounded, navigating both a suppressed animal and a manipulative upbringing.

Across six books — four in the original Ruin quartet and a standalone duet — the series follows Finley and Nyfain from enemies to fated mates, then shifts to Weston and his true mate Aurelia in a Red Riding Hood retelling within the same world. Each arc builds the world's mythology while delivering escalating romantic and magical stakes. The series is a Wall Street Journal bestseller renowned for its passionate fated-mates dynamics and a hilarious secondary cast led by the scene-stealing butler Hadriel.
